MC33340-MC33342
Battery Fast Charge Controller
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 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. Negative Slope V oltage Detection with 4.0 mV Sensitivity Accurate Zero Current Battery V oltage Sensing High Noise Immunity with Synchronous VFC/Logic Programmable 1 to 4 Hour Fast Charge Time Limit Programmable Over/Undertemperature Detection Battery Over and Undervoltage Fast Charge Protection Power Supply Input Undervoltage Lockout with Hysteresis Operating Voltage Range of 3.25 V to 18 V 177 seconds Fast Change Holdoff Time (MC33340) 708 seconds Fast Change Holdoff Time (MC33342) Pb−Free Packages are Available
This device contains 2,512 active transistors.
