SC8933 - Bi-directional Buck Charger Converter

Datasheet Summary

Description

SC8933 is a synchronous buck charger with reverse boost discharging function.

It integrates two N-channel MOSFETs with ultra-low Rdson and can support up to 12V high efficiency charging and discharging operation.

Features

  • I2C interface, so the user can easily control the charging/discharging mode, and program the charging current, charging voltage, output voltage, and output current limits through I2C. It also monitors the VBUS status of up to three USB ports and provides three NMOS gate drivers to control the power path independently. The IC also provides IMON pin, through which the MCU can monitor the VBUS / VBAT voltage, IBUS / IBAT current and the current of each port in real time. The NTC function guarantees.

SOUTHCHIP SEMICONDUCTOR SC8933 DATASHEET SOUTHCHIP CONFIDENTIAL SC8933 High Efficiency, Synchronous, Bi-directional Buck Charger Converter with Integrated MOSFETs and I2C Interface 1 Description SC8933 is a synchronous buck charger with reverse boost discharging function. It integrates two N-channel MOSFETs with ultra-low Rdson and can support up to 12V high efficiency charging and discharging operation. In charging mode, it steps down the input voltage to effectively charge the single cell battery. SC8933 supports trickle charging, constant current (CC) charging and constant voltage (CV) charging management functions automatically. When working in discharging mode (reverse boost mode), it can support up to 12V output and achieve up to 95% efficiency with 3.
