The MC33340 is a monolithic control IC that is specifically designed as a
fast charge controller for Nickel Cadmium (NiCd) and Nickel Metal Hydride
(NiMH) batteries. This device features 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. Provisions for entering a rapid test mode are available to
enhance end product testing. This device is available in an economical
8–lead surface mount package.
