Battery Linear Charger
Setting Charge Current
The charging current can be programmed by a resistor connected from the PROG pin to ground. The battery charging
current is 1200 times the PROG pin flowing out current. The value of required resistor can be calculated by the following
equation:
R_PROG
=
1200
I _{CHG(MAX )}
The instantaneous charging current provided to the battery can be determined by monitoring the PROG pin voltage with
the following equation:
I _CHG
=
1200
