vs Temperature

7.2V Float Voltage

8.4V Float Voltage

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.
