Undervoltage Sensing

Circuit

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 Micro8t 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.
