Introduction

AI Translation

The bq25890 and bq25892 are highly integrated 5A switch-mode battery charging management and system power path management devices suitable for lithium-ion and lithium-polymer batteries. These devices support high-input-voltage fast charging. Their low-impedance power paths optimize the efficiency of switch-mode operation, reduce battery charging time, and extend battery life during the discharge phase. The I²C serial interface with charging and system settings makes these devices a truly flexible solution.
