SLUSFA4B June 2023 – February 2024 BQ25628E
PRODUCTION DATA
The BQ25628E is a highly-integrated 2-A switch-mode battery charge management and system power path management device 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 device uses 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 0.15μA ship mode current extends battery shelf life. The I2C serial interface with charging and system settings makes the BQ25628E a truly flexible solution.
