Battery Fast Charge
Controllers
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
