bq25A - 1-4 Cell Li+ Battery SMBus Charge Controller

Download the bq25A datasheet PDF. This datasheet also covers the bq24725A variant, as both devices belong to the same 1-4 cell li+ battery smbus charge controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The BQ24725A is a high-efficiency, synchronous battery charger, offering low component count for space-constraint, multi-chemistry battery charging applications.

Key Features

  • 1 SMBus Host-controlled NMOS-NMOS synchronous buck converter with programmable 615kHz, 750kHz, and 885kHz switching frequencies.
  • Automatic N-channel MOSFET selection of system power source from adapter or battery driven by internal charge pumps.
  • Enhanced safety features for over voltage protection, over current protection, battery, inductor and MOSFET short circuit protection.
  • Programmable input current, charge voltage, charge current limits.
  • ±0.5% Ch.
