BQ2002FPN TI Battery Charger IC | 8-PDIP | NiCd/NiMH, Fast Charge

Product Overview

The BQ2002FPN 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 PDIP package, it integrates a precision voltage reference, current sense, and charge termination logic. The device supports constant-current and constant-voltage charging with programmable charge current up to 2A. Its wide input voltage range (4.5V to 5.5V) makes it suitable for portable and industrial applications.
