T H E I N F I N I T E P O W E R O F I N N O VAT I O N MC33164-3/MC34164-3 3V UNDERVOLTAGE SENSING CIRCUIT PRODUCTION DATA SHEET DESCRIPTION The MC33164-3 and MC34164-3 are undervoltage 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 capable of sinking more than 6mA over the full temperature range.
