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, MC33064, and NCV33064 are undervoltage sensing circuits designed specifically as reset controllers for microprocessor-based systems. They feature 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 can sink in excess of 10 mA, ensuring reliable operation down to a 1.0 V input.
| Comparator Threshold Voltage (Typical) | 4.6 V at 25°C |
|---|---|
| Reset Output Sink Current | Excess of 10 mA |
| Minimum Guaranteed Input Voltage | 1.0 V |
| Operating Junction Temperature (MC34064) | +150 °C |
