Products Detail

The BQ25820 is a wide input voltage, switched-mode buck Li-Ion, Li-polymer, or LiFePO4 battery charge controller with direct power path control. The device offers high-efficiency battery charging over a wide voltage range with accurate charge current and charge voltage regulation, in addition to automatic charge preconditioning, termination, and charge status indication. The device integrates all the loop compensation for the buck converter, thereby providing a high density solution with ease of use. In reverse mode, the device draws power from the battery and regulates the SYS terminal voltage.

Wide input voltage operating range: 4.4V to 70V
Synchronous buck charge controller with NFET drivers
- Adjustable switching frequency from 200kHz to 600kHz
- Optional synchronization to external clock
- Integrated loop compensation with soft start
- Optional gate driver supply input for optimized efficiency
Bidirectional converter operation (Reverse Mode) supporting USB-PD Extended Power Range (EPR)
- Adjustable input voltage (VAC) regulation from 3.3V to 65V with 20mV/step
- Adjustable input current regulation (RAC_SNS) from 400mA to 20A with 50mA/step using 2mΩ resistor
Direct power path management for highest efficiency to power system
- System power selection from adapter or battery
- Dynamic power management
