Undervoltage Sensing
Circuit
The MC34064 is an undervoltage sensing circuit specifically
designed for use as a reset controller in microprocessorbased
systems. It offers the designer an economical solution for low voltage
detection with a single external resistor. The MC34064 features a
trimmedinpackage 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 3pin TO-92,
micro size TSOP5, 8pin SOIC8 and Micro8 surface mount
packages. The NCV device is packaged in SOIC8 and TO92.
Applications include direct monitoring of the 5.0 V MPU/logic
power supply used in appliance, automotive, consumer and industrial
equipment.
