10 Power Supply Recommendations

The device manages its supply voltage dynamically according to the operation conditions. Normally, the BAT

input is the primary power source to the device. The BAT pin should be connected to the positive termination of

the battery stack. The input voltage for the BAT pin ranges from 2.2 V to 26 V.

The VCC pin is the secondary power input, which activates when the BAT voltage falls below minimum Vcc. This

allows the device to source power from a charger (if present) connected to the PACK pin. The VCC pin should

be connected to the common drain of the CHG and DSG FETs. The charger input should be connected to the

PACK pin.
