Functions
Input current limit
Input current from DCIN pin can be limited to the value set by ILIM_OTG pin or I2C (Refer to the table
below.). When input current exceeds the preset value, the TC7710WBG limits current to below the preset
value automatically. When DCIN voltage turns into below the threshold voltage set by I2C, the TC7710WBG
limits current to the USB100 level (Max 100mA) and indicates an interrupt signal. To resume the current
limit to the former level, the interrupt signal must be cleared (Refer to the command: INTCLR5 (15H, bit5).).
After clearing the interrupt signal, input current limit is set to the former level quickly. For safe use, input
current limit is set to lower value and the interrupt signal can be cleared.

DCIN input voltage protection
When input voltage from DCIN pin exceeds specified voltage (Typ. 6.5V), input is shutdown. Charge is valid
when input voltage is higher than the UVLO and lower than the OVLO. As soon as DCIN input supply is
removed, charge is invalid automatically. Under the condition that charge is invalid, UVLO / OVLO
detection for DCIN pin and OVLO detection for battery voltage are invalid.
7.3
Preliminary charge state
When DCIN input supply is connected, the TC7710WBG check the following items for charge start-up. After
starting charge, charge is suspended when one of the following items is outside the limits
(1) DCIN input voltage ≥ UVLO voltage, DCIN input voltage ≤ OVLO voltage
(2) DCIN voltage > Battery voltage + 100mV
(3) Charge is enabled. (Set by I2C or EN pin. Refer to the command: ENSEL(11H,bit2), ENCMD(11H,bit1),
ENPINPOL(11H,bit0).)
(4) Battery temperature is between high limit and low limit (Refer to the command: TEMPDET(12H,bit7),
BIASCRT1-0(1EH,bit7-6), COLDVTH1-0(1EH,bit3-2), HOTVTH1-0(1EH,bit1-0).).

Trickle charge
Preliminary charge state is OK, the TC7710WBG starts trickle charge with 50mA (Typ.) if battery voltage is
lower than 2.1V.
7.5
Pre-charge
When battery voltage exceeds 2.1V, the TC7710WBG starts pre-charge with the charge current set by the
register. Pre-charge continues until the battery voltage reaches the fast charge threshold voltage set by the
register (Refer to the command: CCVTH2-0(01H,bit2-0).). If the battery voltage is not exceed the fast charge
threshold voltage before the pre-charge timer expires, charge is suspended and an interrupt signal is
indicated (Refer to the command: INTCHGER(20H,bit1), ST_TMER1-0(23H,bit1-0).). If battery voltage is
lower to the trickle charge level during pre-charge, the TC7710WBG becomes trickle charge mode and
indicates an interrupt signal (Refer to the command: INTVBAT(20H,bit6).).In this case, if trickle charge is
invalid (12H,bit0= ”1”), the TC7710WBG doesn’t become trickle charge and doesn’t indicate an interrupt
signal.

When fast charge mode is valid, the TC7710WBG starts constant current charge mode if battery voltage
exceeds the fast charge threshold voltage set by the register. The TC7710WBG limits charge current to
below input current limit value (Refer to the command: CCISET(12H,bit2), PRCCTH(12H,bit1), CCVTH2-0
(01H,bit2-0).). If battery voltage is lower to the pre charge level during fast charge, the TC7710WBG
becomes pre-charge mode and indicates an interrupt signal (Refer to the command: INTVBAT(20H,bit6).).

Charge completion
When charge completion is valid (Refer to the command: CT(12H,bit3).), charging is completed if charge
current is lower than the charge termination current set by the register (Refer to the command:
CEI1-0(00H,bit5-4).). If charge timer has expired until charge is completed, the TC7710WBG terminates the
charge and indicates an interrupt signal (Refer to the command: INTCHGER(20H,bit1),
ST_TMER1-0(23H,bit1-0).). If charge completion is invalid (CT(12H,bit3)=1), the TC7710WBG continues CV
charge and doesn’t indicate an interrupt signal. In this case, the TC7710WBG is controlled by I2C to
terminate the charge. The status ST_CGED0 (24H,bit4) can be checked if charge current is lower than the
current set by the register during CV charge mode.

Re-charge
The TC7710WBG recharges the battery when the battery voltage falls by a value set by the register below
the float voltage (Refer to the command: FLTV6-0(02H,bit6-0), ATRCHGTH(00H,bit6) is fixed to 140mV. ).
The TC7710WBG can recharge only when DCIN input supply is connected, charge is enabled and the charge
start-up condition is satisfied before charge. In this case, the TC7710WBG is controlled by command to
recharge the battery automatically (Refer to the command: ATRCHG(12H,bit4).).

case the battery voltage is higher than dead battery threshold, charge is controlled by EN pin / I2C, and in
case the battery voltage is lower than dead battery threshold, the TC7710WBG starts charge when DCIN
input supply is connected, charge is enabled and the charge start-up condition is satisfied before charge. A
charge enable shall be set after 3ms since the float voltage is set. The TC7710WBG continues charge until
charge is completed or pre-charge safety timer of 36minutes is expired.

7.11 USB OTG
The TC7710WBG can supply a regulated 5V output at the DCIN pin for powering peripherals compliant
with the USB OTG specification (Refer to the command: OTGVCTL1-0(04H,bit5-4).). When only a battery is
connected (AC adaptor or USB isn’t connected) and battery voltage is higher than battery UVLO voltage,
OTG control can be enabled by ILIM_OTG pin or I2C (Refer to the command: OTGUVTH1-0(04H,bit1-0),
OTGMD(13H,bit7), LMT_OTG1-0(13H,bit3-2).). If battery UVLO, battery current limit and DCIN UVLO
are occurred during OTG mode, OTG operation is suspended. OTG operation resumes by ILIM_OTG pin or
I2C. During OTG operation, output current is controlled by a value set by the register (Refer to the
command: CCI4-0(01H,bit7-3).).When output current exceeds the preset value, the TC7710WBG shuts off
the OTG voltage and indicates an interrupt signal (Refer to the command: INTOTGER(20H,bit3),
ST_OTGLM(22H,bit1).). When the chip temperature exceeds 135°C during OTG operation, the TC7710WBG
shuts off the OTG voltage and indicates an interrupt signal (Refer to the command: INTOTGER(20H,bit3),
ST_OTGJCT(22H,bit3).). During OTG operation, a watchdog timer should be valid for system safety. When a
watchdog timer is expired, the TC7710WBG shuts off the OTG voltage and indicates an interrupt signal
(Refer to the command: OTGWDTM(10H,bit4), INTOTGER(20H,bit3), ST_OTWDT(22H,bit2).).

7.12 Watchdog timer
A watchdog timer is reset with every I2C ACK signal transmitted from a system. If watchdog timer is
expired during the charging / OTG operation, the TC7710WBG suspends the charging / OTG operation,
indicates an interrupt signal and reset the following registers: 00H-13H, 1EH, and 1FH (e-Fuse data is
reloaded.). During OTG operation, a watchdog timer should be valid for system safety. And standby
watchdog timer should be valid when the TC7710WBG doesn’t charge or supply OTG power (Refer to the
command: STBWDTM(10H,bit5), OTGWDTM(10H,bit4), CHGWDTM(10H,bit3).). However both watchdog
timers are not valid from a fully charged state to an automatic recharge starts, since the TC7710WBG isn’t
in a charge mode or a standby mode. To set a charge disable, standby watchdog timer is valid for this time.

7.13 Safety timer
The TC7710WBG has a pre-charge timer of 36 minutes and a charge timer of 240 minutes (Refer to the
command: PRCHGTM(10H,bit2), CHGSTM(10H,bit1).). A pre-charge timer of 36 minutes is started after
preliminary charge state is OK, the TC7710WBG starts trickle charge. And this timer is reset when the
mode is changed from pre-charge to fast charge. A charge timer of 240 minutes is also started after
preliminary charge state is OK, the TC7710WBG suspends the charging if charge current isn’t lower than
the charge termination current within a timer. It is possible not to include trickle charge time in the charge
timers (Refer to the command: TCSTON(10H,bit0).). Both timers can be cleared by I2C in case charge timers
are monitored by system (Refer to the command: CHGTMCLR(10H,bit6).). When the TC7710WBG starts
recharge in case an auto recharge is valid, these safety timers aren’t valid. Therefore it is recommended that
an external timer is applied by system for charge protection.

timer indicates charge error interrupt signal (Refer to the command: INTCHGER(20H,bit1),
ST_BATHT(21H,bit1), ST_BATCL(21H,bit0).). And when the temperature becomes within the limit range,
the TC7710WBG resumes charge and charge timer. As detection range is different depending on a
characteristic of NTC thermistor, external resistance which is the same value of R25 is connected in parallel
typically. And the intended range of temperature is set (Refer to the command: COLDVTH1-0(1EH,bit3-2),
HOTVTH1-0(1EH,bit1-0).). The TC7710WBG supports thermistors which value of R25 is 10kΩ, 25kΩ, 50kΩ,
and 100kΩ. A current source of 200µA, 80µA, 40µA, and 20µA is selected depending on the resister (Refer to
the command: BIASCRT1-0(1EH,bit7-6).).

7.18 Power source detection
The TC7710WBG corresponds to Battery Charging Specification Rev1.2. Automatic power source detection
can be set by the register (Refer to the command: ATPSDET(13H,bit4).). Source detection starts as soon as
DCIN is connected. There are four kinds of detection results as follows; non-connection, SDP (Standard
Downstream Port), CDP (Charging Downstream Port), and DCP (Dedicated Charging Port) (Refer to the
command: ST_STYP1-0 (25H,bit1-0).). Input current limit can be set depending on the detection state (Refer
to 7.1 Input current limit.).

7.19 Unconnected battery detection
The TC7710WBG executes battery detection through VBATT pin (Refer to the command:
BATMSDET(11H,bit4).). When battery voltage is lower than 2.1V, the TC7710WBG starts trickle charge.
And when battery voltage exceeds 2.1V, the TC7710WBG starts pre-charge. If battery voltage exceeds 3.3V
within 85ms after starting pre-charge, the TC7710WBG detects as unconnected battery (Refer to the
command: INTCHGER(20H,bit1), ST_BATMS(21H,bit7).).

7.21 Battery save mode
The TC7710WBG becomes battery save mode when DCIN is in UVLO and standby WDT is invalid, or when
OTG is disable. If there are I2C signals among the battery save mode, the TC7710WBG changes the mode to
the standby mode. Wait time 1ms is necessary to write next I2C signal successively. If there is a DCIN input
among the battery save mode, the TC7710WBG enables POR and becomes standby mode.
7.22 I2C Bus
A communication between the TC7710WBG and the host is operated using I2C format. Both the clock line
(SCL) and the data line (SDA) provide a communication between the TC7710WBG and the host. There are
Start Condition and Stop Condition, when they send and receive the data. The commands are sent between
Start Condition and Stop Condition. Refer to the following figure.

7.22.2 Start Condition / Stop Condition
The TC7710WBG is communicated on I2C format. So, the packets divided by Start Condition / Stop
Condition are transmitted and received. The communication consists of SCL (clock line) and SDA (data line).
If they don’t communicate, both clock line and data line are fixed to High level. It goes through Start
Condition that data line goes down earlier than clock line. And it goes through Stop Condition that clock
line goes down earlier than data line. It is prohibited changing condition of the data line, while the clock
line is High level in normal communication.
It regards as the end of the communication, if the receiver doesn’t operate that data line with low level in
the timing which it receives ACK bit. And, after the end of the communication, it is possible to restart from
Start Condition without Stop Condition.
7.22.3 ACK data
The receiver notifies the transceiver of ACK data by receiving 1 byte (8 bits) to indicate its condition. If it is
no problems, it operates data line with low level after the clock of byte 8 (LSB) goes down. If the data
communication error has occurred by any problems, the TC7710WBG reports NACK.
7.22.4 Slave Address
The TC7710WBG can choose the Slave Address that has 8 types by the fixed e-fuse data.

7.23 Cautions in writing I2C register
To avoid a transitional response of operating parameter by I2C register rewriting, the TC7710WBG stops an
internal operation change for about 250µs after I2C register writing. So if I2C register is written successively
in 250µs, internal operation remains stopping in the meantime. And register is written normally.
If programmed parameters are rewritten continuously after writing the charge EN control register and the
OTG control register, charge and OTG operation do not start while I2C register is under writing. So rewrite
parameter first, then rewrite of the EN control register and the OTG control register.
As for reading of I2C register, internal operation does not stop.

- When DCIN = UVLO and standby WDT is invalid, or OTG = Disable, the TC7710WBG becomes the battery save mode.
- If there is an I2C signal among the battery save mode, the TC7710WBG changes the mode to the standby mode.
Wait time 1ms is necessary to write next I2C signal successively.
- If standby WDT is valid by command in the battery save mode, the TC7710WBG cannot resume the battery save mode.
- When the TC7710WBG is communicated by I2C in standby mode or charge mode, register setting is reflect soon, but state transition is occurred 250µs after that.
If I2C command is set successively in 250µs, state transition is occurred 250µs after last communication.
