bq25895M - I2C Controlled Single Cell Fast Charger

Description

The BQ25895M is a highly-integrated 5-A switchmode battery charge management and system power path management device for single cell Li-Ion and Li-polymer battery.

The devices support high input voltage fast charging.

Features

  • High efficiency 1.5-MHz switch mode buck charge.
  • 93% charge efficiency at 2 A and 91% charge efficiency at 3 A charge current.
  • Optimize for high voltage input (9 V / 12 V).
  • Low power PFM mode for light load operations.
  • Boost mode operation with adjustable output from 4.5 V to 5.5 V.
  • Selectable 500-KHz / 1.5-MHz boost converter with up-to 3.1 A output.
  • 93% Boost efficiency at 5 V at 1 A output.
  • Support down-to 2.5V battery.
