BQ25155 - 1-Cell 500-mA Linear Battery Charger

General Description

The BQ25155 is a highly integrated battery charge management IC that integrates the most common functions for wearable and portable devices, namely a charger, a regulated output voltage rail for system power, ADC for battery and system monitoring, a LDO, and push-button controller.

Key Features

  • 1 Linear battery charger with 1.25-mA to 500-mA fast charge current range.
  • 0.5% Accurate I2C programmable battery regulation voltage ranging from 3.6 V to 4.6 V in 10-mV steps.
  • Configurable termination current supporting down to 0.5 mA.
  • 20-V Tolerant input with typical 3.4-V to 5.5-V input voltage operating range.
  • Programmable thermal charging profile, fully configurable hot, warm, cool and cold thresholds.
  • PowerPath management for powering s.
