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
www.DataSheet4lUow.cosmtandby 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.
