1.1 Introduction

The BQ25185EVM is an evaluation kit for the BQ25185 battery charge management IC. The BQ25185 is a resistor controlled, wide-input operating range 1-A linear battery charger with Power Path in a small QFN package with a thermal pad. The BQ25185 integrates the most common functions for industrial and personal electronics applications and provides ultra-low IQ, integrated protections, resistor configurability, TS monitoring, and best thermal performance in a small solution size.

The BQ25185EVM can be evaluated using a micro-USB input and a battery with a 2-pin JST connector. The EVM contains pin headers are provided to connect with power supplies to simulate charging operation. With on-board potentiometers, jumpers, switches, and terminal blocks, different battery charger parameters can be configured. For specific parameters, review the datasheet for how to configure the device.
