5 Summary

This document showcases the capabilities of the BQ25190 linear battery charger for space-constrained applications. The highly integrated device combines multiple power rails, battery charging functionality, ADC, sequencer, and GPIO expansion in a single 2.25mm x 2.75mm WCSP package. The BQ25190 provides an excellent power and charging implementation for wearables, medical devices, and smart trackers where board space is limited, with additional design options available to further minimize the overall solution footprint.
