MC33340P Battery Fast Charge Controllers IC 3.25V to 18V DIP8
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.
