SM6781B数据手册NPC中文资料规格书

描述 Description

The SM6781B is a quick charge control IC for Nickel Metal Hydride (Ni-MH) and Nickel-Cadmium (Ni-Cd) rechargeable batteries. Quick charging ends in response to negative delta voltage detection (-ΔV) 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 SM6781B requires few external components to realize a high-stability quick charge battery charger.
