SC8803 - Bi-directional Buck Charger Controller

General Description

SC8803 is a synchronous buck charger controller.

It is able to effectively manage charging when input voltage is higher than battery voltage.

In charging mode, SC8803 supports trickle charging, constant current (CC) charging and constant voltage (CV) charging management functions automatically.

Key Features

  • Buck charging mode supports charging functions for 1 to 4 battery in series, including trickle charging, CC charging, CV charging and charging termination function.
  • Reverse boost mode operation (discharging mode).
  • Wide input voltage range (VBUS in charging mode): VBAT to 36 V.
  • Wide reverse output range (VBAT in discharging mode) : VBAT to 36 V.
  • Dynamic adjustable discharging voltage by PWM signal.
  • Dynamic adjustable input/output current limits by PWM signal.
  • H.

SOUTHCHIP SEMICONDUCTOR SC8803 DATASHEET SOUTHCHIP CONFIDENTIAL SC8803 High Efficiency, Synchronous, Bi-directional Buck Charger Controller 1 Description SC8803 is a synchronous buck charger controller. It is able to effectively manage charging when input voltage is higher than battery voltage. In charging mode, SC8803 supports trickle charging, constant current (CC) charging and constant voltage (CV) charging management functions automatically. SC8803 supports very wide input and output voltage range. It is suitable for applications of 1 to 4 series battery. The driver voltage is set to 10V to fully utilize external MOSFETs for maximum efficiency. SC8803 supports bi-directional outputs by controlling DIR pin.
