BQ25012RHLR TI Battery Charger IC | 20-VQFN (3.5x4.5) | 4.5V-10V Input, 1A Charge

Product Overview

The BQ25012RHLR is a highly integrated Li-Ion linear charger and dual synchronous step-down converter from Texas Instruments. Designed for space-constrained portable applications, it combines a 1A linear charger with two highly efficient step-down converters in a compact 20-pin VQFN package (3.5mm x 4.5mm). The device operates from an input voltage range of 4.5V to 10V, making it suitable for USB and adapter charging. The charger features thermal regulation, preconditioning, and termination, while the converters provide adjustable output voltages down to 0.9V with up to 95% efficiency.
