3V UNDER
VOLTAGE SENSING CIRCUIT PRODUCTION DATA SHEET
DESCRIPTION
The MC33164-3 and MC34164-3 are under
voltage sensing circuits designed specifically for use as reset controllers in microprocessor-based systems.
They offer the designer an economical, space efficient solution for low supply
voltage detection when used in combination with a single pull-up resistor.
Adding one capacitor offers the functionality of a programmable delay time after power
returns.
The MC33164-3 and MC34164-3 consist of a temperature stable reference comparator with hysteresis, high-current clamping diode and an open collector output stage...
