GND (Bank 1, Pin L7): Power and Signal Ground Return.
BAT (Bank 2): Battery Charge Current Output Bus. The charge
function operates to achieve the final float voltage at this pin.
The auto-restart feature initiates a new charging cycle when
the voltage at the ADJ pin falls 2.5% below the float voltage.
Once the charge cycle is terminated, the input bias current of
the BAT pin is reduced to minimize battery discharge while
the charger remains connected.
VINA (Bank 3): Anode of input reverse protection Schottky
diode. Connect the input power here if input reverse voltage
protection is desired.
VIN (Bank 4): Charger Input Supply. Decouple with at least
4.7μF to GND. Connect the input power here if no input reverse
voltage protection is needed.
BIAS (Pin G7):TheBIASpinconnectstotheinternalpowerbus.
In most cases connect to VBAT. If this is not desirable, connect
to a power source greater than 2.8V and less than 10V.
CHRG (Pin K7): Open-Collector Charger Status Output; typi-
cally pulled up through a resistor to a reference voltage. This
status pin can be pulled up to voltages as high as VIN and can
sink currents up to 10mA. During a battery charging cycle,
CHRG is pulled low. When the charge current falls below C/10,
