The MC33340DR2G from ON Semiconductor is a monolithic control IC specifically designed for fast charging Nickel Cadmium (NiCd) and Nickel Metal Hydride (NiMH) batteries. It utilizes negative slope voltage detection as its primary method for fast charge termination, ensuring accurate sampling by momentarily interrupting the charge current.
This device supports secondary backup termination methods, including programmable time or temperature limits. Protective features are integrated, such as battery over and undervoltage detection, latched over-temperature detection, and power supply input undervoltage lockout with hysteresis. The operating voltage range for this IC is from 3.25 V to 18 V.
The MC33340DR2G is supplied in an 8-SOIC surface mount package, making it suitable for various electronic designs. Its fast charge holdoff time is typically 177 seconds, differentiating it from similar parts like the MC33342.
Key specifications include a negative slope voltage detection sensitivity of 4.0 mV, accurate zero current battery voltage sensing, and high noise immunity. It also features programmable fast charge time limits from 1 to 4 hours and programmable over/undertemperature detection.
