3 Description
The BQ25628 and BQ25629 are highly-integrated
2-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), lowside
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 0.15-μA
ship mode current extends battery shelf life. The I2C
serial interface with charging and system settings
makes BQ25628 and BQ25629 truly flexible solutions.
