Ni-MH/Ni-Cd Battery Charger IC
OVERVIEW
The SM6781BV is a quick charge control IC for Nickel Metal Hydride (NiMH) and Nickel-Cadmium (NiCd)
rechargeable batteries. Quick charging ends in response to negative delta voltage detection (–
mum charging time detection functions. Also, quick charge mode is placed on hold if the battery voltage
becomes abnormal, until normal conditions are restored. The SM6781BV requires few external components to
realize a high-stability quick charge battery charger.
