Power\Power Management ICs\Battery Managementbq25620/bq25622 Buck Battery Chargers Texas Instruments bq25620/bq25622 Buck Battery Chargers are highly integrated 3.5A 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. It 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, and extends battery life during the discharging phase. The ultra-low 0.15µA ship mode current extends battery shelf life. The I2C serial interface with charging and system settings make the Texas Instruments bq25620/bq25622 truly flexible solutions.
