SC8813 - Bi-directional Buck Charger Controller

General Description

SC8813 is a synchronous buck charger controller with reverse boost discharging function.

It supports very wide input and output voltage range, suitable for applications of 1 to 4-cell Li-ion battery.

Key Features

  • I2C interface, so the user can easily set the charging/discharging mode and program the input current limit, output current limit and output voltage through I2C. It also supports DP/DM handshaking, the adapter insert detection function, load insert detection function, small current detection. Meantime, it offers a PMOS gate driver for external power path control, an open drain output for general purpose, and also a 10-bit ADC resource. The user can control all these functions through I2C. All th.

SOUTHCHIP SEMICONDUCTOR SC8813 DATASHEET SOUTHCHIP CONFIDENTIAL SC8813 High Efficiency, Synchronous, Bi-directional Buck Charger Controller with I2C Interface 1 Description SC8813 is a synchronous buck charger controller with reverse boost discharging function. It supports very wide input and output voltage range, suitable for applications of 1 to 4-cell Li-ion battery. In charging mode, it steps down the input voltage and effectively charging the batteries as long as the input voltage is higher than battery voltage. SC8813 supports trickle charging, constant current (CC) charging and constant voltage (CV) charging management functions automatically. In discharging mode (reverse boost mode), SC8813 is able to output a boosted voltage up to 36V effectively.
