The MC34064D-005G is an under-voltage Sensing Circuit specifically designed for use as a reset controller in microprocessor-based systems. It offers the designer an economical solution for low voltage detection with a single external resistor. It features a bandgap reference, a comparator with precise thresholds and built-in hysteresis to prevent erratic reset operation. The open collector reset output is capable of sinking in excess of 10mA and operation is guaranteed down to 1V input with low standby current.
