BQ2003S-N TI Battery Charger IC | 16-SOIC | NiCd/NiMH, Fast Charge

Product Overview

The BQ2003S-N from Texas Instruments is a high-performance, low-dropout (LDO) linear battery charger IC designed for fast charging of NiCd and NiMH batteries. It integrates a precision voltage reference, current sense amplifier, and charge termination logic in a compact 16-SOIC package. The device supports constant-current (CC) and constant-voltage (CV) charging modes, with programmable charge current up to 2A. Its low dropout voltage (typically 0.5V at 1A) ensures efficient operation even with low input voltages. The BQ2003S-N is ideal for portable electronics, power tools, and industrial equipment requiring reliable and safe battery charging.
