SC8802 is a synchronous 4-switch buck-boost charger
controller. It is able to effectively manage charging no matter
input/output voltage is higher, lower or equal to battery
voltage. When system needs to discharge from battery,
SC8802 will deliver desired output from the battery without
extra efforts.
SC8802 supports very wide input and output voltage range. It
can support applications from 2.7V to 30V input range and 2V
to 30V output range. SC8802 hence is suitable for
applications of 1 to 6 series battery modules. The driver
voltage is set to 10V to fully utilize external MOSFETs for
maximum efficiency.
SC8802 supports bi-directional outputs by controlling DIR pin.
It supports input current limit, output current limit, dynamic
output voltage regulation, internal current limit, output short
protection and over temperature protections to ensure safety
under different abnormal conditions.
