ETA6963

I²C Controlled 13.5V/3A, 1-Cell Battery Charger with Power Path

Management and USB Charger Detection

DESCRIPTION

FEATURES

ETA6963 is a highly-integrated 3A switch-mode battery

charge and system power path management device for

single cell Li-Ion and Li-polymer battery. It features fast

charging with high input voltage support for a wide range

of smart phones, tablets and portable devices. Its low

impedance power path optimizes switch-mode

operation efficiency, reduces battery charging time and

extends battery life. Its input voltage and current

regulation deliver maximum charging power. The

solution is highly integrated with input reverse-blocking

FET, high/low-side switching FET, and battery FET. It

also integrates the bootstrap diode for the high-side gate

drive. The I2C serial interface with charging and system

settings makes the device a truly flexible solution. The

device supports a wide range of input sources. The

device is compliant with USB 2.0 and USB 3.0 power

spec with input current and voltage regulation. The

device also meets USB On-the-Go (OTG) operation

power rating specification by supplying 5.15 V on BUS

pin with constant current limit up to 1.2A.The power path

management regulates the system slightly above

battery voltage but does not drop below 3.5 V minimum

system voltage (programmable). With this feature, the

system maintains operation even when the battery is

completely depleted or removed. When the input current

limit or voltage limit is reached, the power path

management automatically reduces the charge current

to zero. As the system load continues to increase, the

power path discharges the battery until the system

power requirement is met. This Supplement Mode

prevents overloading the input source.
