SC8815 High Efficiency, Synchronous, Bi-Directional Buck-Boost

Charger Controller with I2C Interface

1 Description

generate an output from the battery, SC8815 can also

discharge the cells and delivers desired output up to

36V.

Through its I2C interface, user can set the charging /

discharging mode easily, and program the charging

current, charging voltage, reserve output voltage,

current limits, switching frequency and other

parameters flexibly. Besides that, SC8815 integrates

10-bit ADC, so user can read the VBUS / VBAT voltage

and current in real time, simplifying the system design.
