Pin Functions
resistor, RPROG, to ground. When charging in constant
current mode, this pin servos to 1V. The voltage on this
pin can be used to measure the charge current using the
following formula:

VCC (Pin 10): Positive Input Supply Voltage. Provides
power to the battery charger. This pin should be bypassed
with a 1µF capacitor.
GND (Exposed Pad Pin 11): Ground. This pin is the back
of the exposed pad package and must be soldered to the
PCB copper for minimal thermal resistance.
