SM6781BV

Ni-MH/Ni-Cd Battery Charger IC

NIPPON PRECISION CIRCUITS INC.

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 (–∆V) and maxi-

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.
