Datasheet Summary
3.2 A Dual Input, Switch Mode Charger with Power Path
Description The FAN5451x family of chargers includes an I2C controlled 3.2 A
USB- pliant switch- mode charger. To facilitate fast system startup, the IC includes an optimized Power
Path circuit which also accurately measures battery currents during charging and provides low impedance during discharge.
The charging parameters and operating modes are programmable through an I2C Interface. Charge status is reported back to the host through the I2C port and the / STAT pin.
The FAN5451x provides battery charging in three modes: Pre- Charge (IPP), Constant Current (CC) and Constant Voltage (CV). The charger can automatically...
