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.

■ – 4mV (typ) −∆V detection accuracy
■ Inhibit function
■ Charge condition LED indicator output (on, pulsed, off)
■ Low power dissipation standby mode (< 1µA)
■ 8-pin VSOP package
