BQ2000PW TI Battery Charger IC | 8-TSSOP | NiCd/NiMH, Fast Charge

Product Overview

The BQ2000PW 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 a compact 8-pin TSSOP package, it integrates a precision voltage reference, current sense, and charge termination logic. The device supports constant-current (CC) and constant-voltage (CV) charging 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 BQ2000PW includes safety features such as temperature monitoring, charge timeout, and reverse battery protection, making it ideal for portable and industrial applications.
