BQ2002E Datasheet (UNITRODE) - NiCd/NiMH Fast-Charge Management

BQ2002E, NiCd/NiMH Fast-Charge Management

The bq2002E and bq2002G FastCharge 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 bq2002E/G to be the basis for a costeffective stand-alone or syst

BQ2002E Features
