SC8803 Overview
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 Key Features
- Buck charging mode supports charging functions for 1 to 4 battery in series, including trickle charging, CC charging, CV

- Wide input voltage range (VBUS in charging mode)
- Wide reverse output range (VBAT in discharging mode)
- Dynamic adjustable discharging voltage by PWM signal
- Dynamic adjustable input/output current limits by PWM
- High efficient buck/boost operation
- Integrated 10V, 2A gate driver
- Adjustable frequency from 200KHz to 600KHz
