BQ25125 - Highly Integrated Battery Charger

Datasheet Summary

Description

The BQ25125 is a highly integrated battery charge management IC that integrates the most common functions for wearable devices: Linear charger, regulated output, load switch, manual reset with timer, and battery voltage monitor.

Features

  • Increases system operation time between charges.
  • Configurable 300-mA buck regulator (1.8 V default).
  • 700-nA (typical) Iq with buck converter enabled (No Load).
  • Configurable load switch or 100-mA LDO output (1.8 V default).
  • Up to 300-mA charge current for fast charging.
  • 0.5% Accurate battery voltage regulation (configurable from 3.6 V to 4.65 V in 10-mV steps).
  • Configurable termination current down to 500 µA.
  • Simple voltage.
