Multi-chemistry charge controller in 8-SOIC
The BQ2002CSN is a Texas Instruments battery charge controller supporting multi-chemistry cells — NiCd, NiMH, Li-Ion, or lead-acid — with a constant or pulsed current charging algorithm and a programmable voltage termination threshold. It is supplied in an 8-SOIC surface-mount package (0.154" body width, 3.90 mm) and ships in tube format, suitable for medium-volume pick-and-place assembly. The maximum supply voltage is 6 V, and the battery pack voltage is limited to 2 V — typical for a single-cell Li-Ion or two-cell NiMH/NiCd series.
