Introduction

TC4058H is a lithium battery charging power management IC that supports AC adapter or USB interface as power input; when the power source is removed, TC4058H enters sleep mode. TC4058H charges in a linear manner, featuring a three-stage full-process charging sequence — trickle charge, constant current, and constant voltage — with flexible charge current setting via an external resistor. TC4058H incorporates multiple protection features, including input overvoltage protection and chip overtemperature protection. TC4058H is currently available in SOT23-5L, SOT23-6L, ESOP8, and DFN-6 packages.
