The 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. The MC devices are packaged in 3-pin TO-92, micro size TSOP?5, 8?pin SOIC?8 and Micro8 surface mount packages. The NCV device is packaged in SOIC-8 and TO-92.
Applications of MC34064 include direct monitoring of the 5.0 V MPU/logic power supply used in appliance, automotive, consumer and industrial equipment.
