BQ24401D TI Battery Charger IC | 8-SOIC | NiCd/NiMH, 1-4 Cells

Product Overview

The BQ24401D from Texas Instruments is a complete constant-current, constant-voltage linear charger for single-cell and multi-cell NiCd and NiMH batteries. It is designed for applications requiring a simple, low-cost charging solution with minimal external components. The device operates from a supply voltage up to 6.5V and can charge 1 to 4 series cells. It features a programmable charge current up to 2A and includes automatic charge termination based on negative delta voltage (-ΔV) and temperature monitoring. The 8-SOIC package offers a compact footprint for space-constrained designs.
