MC34064 is an undervoltage 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. The MC34064 features a trimmed−in−package bandgap reference, and 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 10 mA, and operation is guaranteed down to 1.0 V input with low standby current.
