欠压检测电路NCV33064D-5R2

　　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 include direct monitoring of the 5.0 V MPU/logic power supply used in appliance， automotive， consumer and industrial equipment.
