BQ25620 - Buck Battery Charger

Description

The BQ25620 and BQ25622 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.

Features

  • High-efficiency, 1.5MHz, synchronous switching mode buck charger for single cell battery.
  • >90% efficiency down to 25mA output current from 5V input.
  • Charge termination from 10mA to 620mA, 10mA steps.
  • Flexible JEITA profile for safe charging over temperature.
  • BATFET control to support shutdown, ship mode and full system reset.
  • 1.5μA quiescent current in battery only mode.
  • 0.15μA battery leakage current in ship mode.
  • 0.1μA ba.
