SOUTHCHIP南芯 SC8982QFMR QFN 22+

　　1 Descriptions

　　SC8982 is a highly integrated buck-boost charger optimized

　　for 1~2 cell Li-ion and Li-polymer batteries. It integrates 4

　　switching power MOSFETs for the buck-boost operation, and

　　can support up to 22V input voltage, so can be used to

　　effectively manage the charging process no matter adapter

　　voltage is higher, lower or equal to battery voltage. The IC can

　　also discharge the cells and deliver desired output up to 21V.

　　The IC also integrates the battery FET to support the NVDC

　　(Narrow VDC) power path management. It provides a highdensity battery charging solution for the smart phone, tablet

　　and other portable devices and supports the USB type-C PD

　　(Power Delivery) charging easily.

　　The IC integrates a 10-bit ADC so user can monitor the

　　voltage and current for both inputs, system output and also

　　the battery easily. Through its I2C interface, user can set the

　　charging / discharging mode easily, and program the charging

　　current, charging voltage, system voltage, reserve output

　　voltage, current limits and other parameters flexibly.

　　The IC supports internal current limit, over voltage protection,

　　output short protection and over temperature protections to

　　ensure safety under abnormal conditions.

　　The IC is in a 30-pin 4mm x 5mm QFN package.
