Descriptions

SC8910 is a synchronous buck-boost charger converter which also supports reverse discharging operation. Four switches are integrated to simplify the system design. SC8910 employs current-mode control and can support very wide input and output voltage range. It can support applications from 3.6V to 22V VBUS range. It is able to effectively manage charging for 2~4 cell batteries no matter input/output voltage is higher, lower or equal to battery voltage. When system needs to discharge from battery, the IC will deliver desired output from the battery.

Through its I2C interface, user can set the charging / discharging mode easily, and program the charging current, VINREG voltage, reversed output voltage, current limits, switching frequency and other parameters flexibly. Charging voltage can be adjusted by external resistor.

SC8910 supports internal current limit, under voltage protection, over voltage protection, output short protection and over temperature protections to ensure safety under abnormal conditions.

The IC is in a 21 pin 4x4 QFN package.
