BQ2002CSN TI Battery Charger IC | 8-SOIC | NiCd/NiMH, Fast Charge

Product Overview

The BQ2002CSN from Texas Instruments is a high-performance, low-dropout (LDO) linear battery charger IC designed for fast charging of NiCd and NiMH batteries. Housed in an 8-pin SOIC package, this device integrates a precision voltage reference, current sense amplifier, and charge termination logic to deliver a complete charging solution. It supports constant-current and constant-voltage charging modes with programmable charge current up to 2A. The BQ2002CSN features automatic charge termination based on negative delta voltage (-ΔV) and maximum temperature, ensuring safe and efficient charging. Its wide input voltage range (4.5V to 5.5V) makes it suitable for portable electronics, power tools, and industrial applications.
