Overview

The BQ21080 is a linear battery charger IC focusing on small solution size and low quiescent current for extending battery life. The device is available in an 8-ball chipscale package which does not need HDI PCB process for fabrication thereby reducing the PCB cost. The device can support up to 800-mA charging and system loads of up to 2.5 A. The battery is charged using a standard Li-ion or LiFePO4 charge profile with three phases: precharge, constant current and constant voltage. Thermal regulation provides the maximum charge current while managing the device temperature. The charger is also optimized for battery to battery charging with 3-V minimum input voltage operation and can withstand 25-V absolute maximum line transients. The device integrates a single push-button input and reset circuitry to reduce the total solution footprint.

Applications

TWS headset and charging case
Smart glasses, AR and VR
Smart watches and other wearable devices
Retail automation and payment
