Overview

The BQ25155EVM evaluation module (EVM) is an integrated battery charge management IC that integrates the most common functions for wearable devices: linear charger, regulated output, load switch, manual reset with timer, ADC, ship mode and advanced power path. The low quiescent current during operation and shutdown enables maximum battery life. The device supports charge currents from 1.25 mA to 500 mA. The input current limit, charge current, regulated PMID output, LDO output voltage and other parameters are programmable through the I²C interface. The device also has a multi-point ADC to measure different parameters on the charger and also includes an optional ADC input. The battery is charged using a standard Li-ion charge profile with three phases: precharge, constant current and constant voltage.

Features

Configurable battery charger
Multi point ADC to measure seven channels
Advanced power path to power system through either battery or adapter
Programmable hard and soft reset
0.5% accurate battery voltage regulation
Wake timers for push button
