Description

General part information

FAN54511 Series

The FAN5451x family of battery charge controllers includes an I2C 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 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 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.
