Order this document by MC33340/D MC33340 Advance Information Battery Fast Charge Controller The MC33340 is a monolithic control IC that is specifically designed as a BATTERY FAST CHARGE fast charge controller for Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries. This device features negative slope voltage detection as CONTROLLER the primary means for fast charge termination. Accurate detection is ensured by an output that momentarily interrupts the charge current for precise voltage sampling. An additional secondary backup termination method can SEMICONDUCTOR be selected that consists of either a programmable time or temperature limit. TECHNICAL DATA Protective features include battery over and undervoltage detection, latched over temperature detection, and
