PQ8808

Synchronous, 80V Bi-directional Buck-Boost Charger Controller with I2C interface and MPPT

PQ8808 is a synchronous buck-boost charger, which supports buck mode, boost mode and buck-boost mode during forward charging or reverse discharging operation. PQ8808 manages multi types of battery charging from wide input range from 4.5V to 80V, supporting trickle charge, pre-charge, constant current charge, constant voltage charge and autonomous termination. The battery discharging mode supports wide output range from 5V to 48V. PQ8808 also provides input current and battery current monitoring function.
