SM6781BV - Ni-MH/Ni-Cd Battery Charger IC

General Description

Timer mode select input (3-level) HIGH and LOW levels applied using pull-up and pull-down, respectively.

MID-level is applied using a voltage divider resistor network with voltage VDD/2.

Charge status display LED driver output (open-drain output) LOW-level output in quick charge mode.

SM6781BV NIPPON PRECISION CIRCUITS INC. 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 (–∆V) and maximum 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.
