CHAPTER 1
GENERAL DESCRIPTION
The GL888E is a USB fast-charging controller which complies with USB Battery Charging Specification
(abbrev. as BC). Before the USB BC is released, most handheld devices have different charging mechanisms that
are not compliant with each other. Generally speaking, old wall-chargers are useless when you have new
handheld devices. Now with a USB enabled wall-charger, it provides unified charging mechanism by traditional
USB current supply (0.5A) when charging devices through USB ports. With a USB enabled wall-charger which
complies with USB BC, it provides unified charging mechanism by more USB current supply (up to 1.5A) when
charging devices through USB ports, so called “fast-charging” mechanism. In another word, GL888E is a high
performance solution for “fast-charging” mechanism and it saves at most 66% of charging time.
Desktop, notebooks, netbooks and LCD TVs/Monitors are commonly used to provide charging current to
handheld devices through USB ports. They stand as the current source from host side like wall-charger, so
GL888E can also be applied for “fast-charging” mechanism under these systems.
In addition, the GL888E will automatically detect and charge not only USB BC compliant devices, but also
Apple/Samsung/RIM devices. This feature implies wide range of end product applications and provides design
flexibility for system manufactures.

CHAPTER 4
RECOMMENDED USAGE SCENARIO
According to different scenario, select an appropriate charge mode will provide better user experience. The
suggestion of the GL888E charge mode selection on desktop and notebook application are described here.
4.1 Desktop and System with AC Power
Table 4.1 – Suggested Usage Scenario on Desktop
System Mode
Operation (S0)
Sleep/Power-off (S3/S4/S5)
Charging Mode Selection
CDP mode
Auto-mode
Description
For S0, the USB host controller is
active and the system is responsible
for sourcing at least 1.5A when CDP
mode is selected.
If the connected device is non-BC
compliant, there is no BC handshake
between host and device. So the
connected device will only draw
current under 500mA.
For S3/S4/S5, only device charging
function is necessary. Auto-mode will
switch to appropriate charge mechanism
depends on the connected device.

compliant, there is no BC handshake
between host and device. So the

NB battery could selectively support
device charging depends on system
design.
Auto-mode is suggested if NB battery
mode must support device charging.

Figure 5.1 – Block Diagram
Figure 5.1 shows the architecture of GL888E, which supports different kinds of charger mechanism, including
USB BC 1.2 SDP/CDP/DCP, Apple 1A/2A wall charger, and Samsung Galaxy Tab wall charger. In auto mode, it
can automatically detect the type of connected device, and switch to appropriate charging mode. When user
changes the charging mode, GL888E will control the external power switch via PSW_EN_OUT pin to
renegotiate with the device. The high bandwidth data switch between UP port and DOWN port reduces the side
effect of USB signal integrity as much as possible.
GL888E is designed for low standby power application. For the system with AC power, the ultra low power
consumption of GL888E doesn’t increase the system suspend current. And for the system with battery power,
GL888E doesn’t impact the system standby time as well.

Support by GL888E Auto mode
Battery Charging Specification defines three charging ports: SDP, CDP and DCP. The SDP is a standard USB
port which can transfer data and provide maximum 500mA (for USB2.0) or 900mA (for USB3.0) current. The
purpose of CDP is to replace SDP, so it can charge device with higher current (up to 1.5A) even during USB data
transfer. The DCP is only a dedicated charging port which supports high current without data transfer. The BC
1.1/1.2 compliant device is able to be charged whether it connects to CDP or DCP.
The CDP mode has Smart CDP feature that GL888E will internally switch to SDP mode when the connected
device is not completely compatible with CDP. The CDP mode also provides USB low speed keyboard/mouse
wake up feature to wake up the system from S3 via the port with GL888E.
Two Apple wall charging modes for Apple devices: “Apple 1A” is for lower battery capacity device, such as
iPhone, iPod, and “Apple 2A” is for higher battery capacity device, such as iPad series. Most up-to-date Apple
devices comply with both types of charging modes, so “Apple 2A” mode is recommended. Please be noted that
the charging current is controlled by device itself, so connecting iPhone to a host under “Apple 2A” charging
mode may not cause iPhone draw higher charging current than under “Apple 1A” charging mode.
Samsung Galaxy Tab has a dedicated charging behavior. To support this series of tablet, GL888E also provides
“Samsung Tablet” mode. However, in order to be backward compatible with previous GL888, this mode is only
supported within Auto mode instead of a dedicated charging mode that can be selected externally.
When setting “Auto 1A” mode, GL888E will automatically detect the connected device and switch between DCP,
“Apple 1A”, and “Samsung Tablet” mode to charge, whereas “Auto 2A” mode will switch between DCP, “Apple
2A”, and “Samsung Tablet” mode. To support most up-to-date devices, “Auto 2A” mode is strongly
recommended.
