BQ2002 Datasheet (Benchmarq) - NiCd/NiMH Fast-Charge Management

BQ2002, NiCd/NiMH Fast-Charge Management

The bq2002 and bq2002/F Fast-Charge ICs are low-cost CMOS battery-charge controllers providing reliable charge termination for both NiCd and NiMH battery applications.

Controlling a current-limited or constant-current supply allows the bq2002/F to be the basis for a cost-effective stand-alone or sys
