Description

The BQ25620 and BQ25622 are highly-integrated 3.5-A switch-mode battery charge management and system power path management devices for single cell Li-Ion and Li-polymer batteries. The solution is highly integrated with built-in current sensing, loop compensation, input reverse-blocking FET (RBFET, Q1), high-side switching FET (HSFET, Q2), low-side switching FET (LSFET, Q3), and battery FET (BATFET, Q4) between system and battery. The devices use narrow VDC power path management, regulating the system slightly above the battery voltage without dropping below a configurable minimum system voltage. The low impedance power path optimizes switch-mode operation efficiency, reduces battery charging time, extends battery life during discharging phase, and the ultra-low 0.15-µA ship mode current extends battery shelf life. The I²C serial interface with charging and system settings makes the BQ25620 and BQ25622 truly flexible solutions.
