Microsemi Corporation MC34164-3DM

Description
The MC33164-3 and MC34164-3 are undervoltage sensing circuits designed for use as reset controllers in microprocessor-based systems. They offer an economical and space-efficient solution for low supply voltage detection when used with a single pull-up resistor. Adding a capacitor provides a programmable delay time after power returns. The MC33164-3 and MC34164-3 consist of a temperature-stable reference comparator with hysteresis, a high-current clamping diode, and an open collector output stage capable of sinking more than 6mA over the full temperature range. The RESET output is specified to be fully functional at VIN ≥ 1V.
