3.2 A Dual Input, Switch

Mode Charger with Power

Path

Description

www.onsemi.com

The FAN5451x family of chargers includes an I C controlled 3.2 A

USB−compliant 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 I C Interface. Charge status is reported back to the host

through the I C 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 restart the charge cycle when the

battery falls below a restart voltage threshold. If the input source is

removed, the IC enters a high−impedance mode, blocking battery

current from leaking to either input.
