UC3906Q TI Battery Charger Controller | 20-PLCC (9x9) | 40V, 25mA

Product Overview

The UC3906Q from Texas Instruments is a complete, sealed lead-acid battery charger controller in a compact 20-PLCC (9x9) package. It integrates all necessary functions for efficient and safe charging, including voltage regulation, current limiting, and status monitoring. Designed for 6V and 12V battery systems, it operates from a supply voltage up to 40V and delivers a maximum charge current of 25mA (external pass transistor required for higher currents). The device features three-state charge control (bulk, overcharge, float) and provides logic outputs for charge status indication.
