Load Switch IC with Current Limit function
The TCK104G and TCK105G are load switch ICs for power
management with slew rate control driver and current limit
function featuring wide input voltage operation from 1.1 to 5.5 V.
Switch ON resistance is only 50 mΩ typical at 5.0V, -700mA load
condition and these feature a slew rate control driver, thermal
shutdown and output auto-discharge function. Output current
type is available on -500mA, and -800mA. Thus it is easy to
select devices and helpful for the design.
This device is available in 0.4 mm pitch ultra small package
WCSP6B (0.8 mm x 1.2 mm, t: 0.64 mm (max)) .Thus this
devices is ideal for portable applications that require high-density
board assembly such as cellular phone.

Note : Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the
significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if
the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum
ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability
Handbook (“Handling Precautions”/“Derating Concept and Methods”) and individual reliability data (i.e.
reliability test report and estimated failure rate, etc).

1) Input capacitor
An input capacitor(CIN) is not necessary for the guaranteed operation of TCK104G and TCK105G. However, it is
recommended to use input capacitors to reduce voltage drop due to sharp changes in output current and also for
improved stability of the power supply. When used, place CIN as close to VIN pin to improve stability of the power
supply. Also, due to the CIN selected, VIN < VOUT may occur, causing a reverse current to flow through the body
diode of the pass-through p-ch MOSFET of the load switch IC. In this case, a higher value for CIN as compared to
CL is recommended.
2) Output capacitor
An output capacitor (COUT) is not necessary for the guaranteed operation of TCK104G and TCK105G. However,
there is a possibility of overshoot or undershoot caused by output load transient response, board layout and
parasitic components of load switch IC. In this case, an output capacitor with COUT more than 0.1μF us
recommended.
3) Control pin
A control pins for TCK104G and TCK105G are both Active High, which controls both the pass-through p-ch
MOSFET and the discharge n-ch MOSFET, operated by the control voltage and Schmitt trigger. When the control
voltage level is High, p-ch MOSFET is ON state and n-ch MOSFET is OFF state. When control voltage level is
Low, and the state of the MOSFETs is reversed. Also, pull down resistance equivalent to a few MΩis connected
between CONTROL and GND, thus the load switch IC is in OFF state even when CONTROL pin is OPEN. In
addition, CONTROL pin has a tolerant function such that it can be used even if the control voltage is higher than
the input voltage.

Please allow sufficient margin when designing a board pattern to fit the expected power dissipation. Also take into
consideration the ambient temperature, input voltage, output current etc and applying the appropriate derating for
allowable power dissipation during operation.
3. Current limit and Thermal shut down function
Current limit and Thermal shutdown function are designed in these products, but these does not assure for the
suppression of uprising device operation. In use of these products, please read through and understand dissipation
idea for absolute maximum ratings from the above mention or our ‘Semiconductor Reliability Handbook’. Then use
these products under absolute maximum ratings in any condition. Furthermore, Toshiba recommend inserting failsafe
system into the design.
