The MC33340 and MC33342 are monolithic control IC’s that are  
specifically designed as fast charge controllers for Nickel Cadmium (NiCd)  
and Nickel Metal Hydride (NiMH) batteries. These devices feature negative  
slope voltage detection as 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 be selected that consists of either a  
programmable time or temperature limit. Protective features include battery  
over and undervoltage detection, latched over temperature detection, and  
power supply input undervoltage lockout with hysteresis. Fast charge holdoff  
time is the only difference between the MC33340 and the MC33342. The  
MC33340 has a typical holdoff time of 177 seconds and the MC33342 has a  
typical holdoff time of 708 seconds.
