Overview

The BQ21061 evaluation module (EVM) is an integrated I²C controlled 1-cell 500-mA PowerPath linear battery charger with LDO and low I_Q to maximize battery life. The device supports charge currents from 1.25 mA to 500 mA. The input current limit, charge current, LDO, regulated output and other parameters are programmable through the I²C interface. The battery is charged using a standard li-ion charge profile with three phases: precharge, constant current and constant voltage.

Features

Configurable battery charger
Advanced PowerPath to power system through either battery or adapter
Pushbutton reset
High accuracy battery voltage regulation
Regulated and configurable output with LDO
