SC8812A is a synchronous buck-boost charger controller which can support reverse discharging operation.It can support up to 26V battery voltage, so can be used toeffectively manage the chargingprocessfor 1~4cell Li-ion batteries no matter adaptervoltage is higher, lower or equal to battery voltage.When a system needs to generate an output from the battery, SC8812Acan also discharge the cells and deliversdesired outputup to 36V.ThroughitsI2C interface,user cansetthe charging/discharging modeeasily, and program the charging current, charging voltage, reserve outputvoltage, current limits, switching frequencyandother parametersflexibly. Besides that, SC8812Asupports fast charging handshake. It also integrates 10-bit ADC, so user can read the VBUS / VBAT voltage and current in real time, simplifying the system design. SC8812Asupportsinternal current limit, over voltage protection, output short protection and over temperature protections to ensure safety under abnormal conditions.The SC8812A is in a 32 pin 4x4 QFN package.
