BQ25120AYFPR

Battery Chargers Overview

The BQ25120AYFPR is an integrated battery charge management IC designed for wearable devices and IoT applications. It combines a linear charger, regulated output, load switch, manual reset with timer, and battery voltage monitor. The device features a high-efficiency buck converter using DCS control, supporting charge currents from 5mA to 300mA. Key parameters include a configurable 300mA buck regulator with a default output of 1.8V, a quiescent current of 700nA (typical) with the buck enabled, and a configurable load switch or 100mA LDO output. Battery voltage regulation accuracy is 0.5%, configurable from 3.6V to 4.65V in 10mV steps. The input voltage range is 3.4V to 5.5V, with 20V tolerance. It operates within a temperature range of -40°C to +125°C and is housed in a 2.5mm × 2.5mm WCSP package.
