PQ8984

I2C Controlled 5A Buck-Boost NVDC Charger Converter for 2~4 Cell Battery with Dual-Input Power-Path and OTG Function

PQ8984PQ8984

PQ8984

PQ8984 is a highly integrated buck-boost charger optimized for 2~4 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 22V. 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.
