MC3425
Power Supply Supervisory/ Over and Undervoltage Protection Circuit
The MC3425 is a power supply supervisory circuit containing all
the necessary functions required to monitor over and undervoltage
fault conditions. These integrated circuits contain dedicated over and
undervoltage sensing channels with independently programmable
time delays. The overvoltage channel has a high current Drive Output
for use in conjunction with an external SCR Crowbar for shutdown.
The undervoltage channel input comparator has hysteresis which is
externally programmable, and an open−collector output for fault
indication.
• Dedicated Over and Undervoltage Sensing • Programmable Hysteresis of Undervoltage Comparator • Internal 2.
