UC3901D TI Battery Charge Controller | 14-SOIC | 1.5% Reference, 500μA

Product Overview

The UC3901D from Texas Instruments is a precision battery charge controller designed for sealed lead-acid (SLA) batteries. It integrates all necessary functions for constant-current/constant-voltage (CC/CV) charging with temperature compensation. Housed in a compact 14-SOIC package, it operates from a 4.5V to 40V supply and features a 1.5% accurate voltage reference. The device ensures optimal battery life and safety by preventing overcharge and deep discharge.
