Features & Applications

The MC34064 is an undervoltage sensing circuit specifically designed for use as a reset controller in microprocessor−based systems.

The MC34064 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 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.

Key Features:

  • Trimmed−In−Package Temperature Compensated Reference
  • Comparator Threshold of 4.6 V at 25°C
  • Precise Comparator Thresholds Guaranteed Over Temperature
  • Comparator Hysteresis Prevents Erratic Reset
  • Reset Output Capable of Sinking in Excess of 10 mA
  • Internal Clamp Diode for Discharging Delay Capacitor
  • Guaranteed Reset Operation with 1.0 V Input
  • Low Standby Current
  • Economical TO−92, TSOP−5, SOIC−8 and Micro8 Surface Mount Packages
  • NCV Prefix for Automotive and Other Applications Requiring Site and Control Changes
  • Pb−Free Packages are Available
