NCV33064: Voltage Supervisor, Undervoltage Sensing Circuit, 4.59 V, with Active Low Open Collector Output, Qualified for 5.0 V Systems

The MC33064/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 voltagedetection with a single external resistor. The MC33064/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-pinTO-226AA, 8-pin SO-8,Micro-8 and 5pin SOT-23/TSOP-5 surface mount packages. The NCV device is packaged in SO-8 and TO-226AA. Applications include direct monitoring of the 5.0 V MPU/logic power supply used in appliance, automotive, consumer and industrial equipment.
