MC33340, MC33342 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 under
voltage detection, latched over temperature detection, and power ...
