Undervoltage Sensing
Circuit
1
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 t 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
