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.
