Order this document by MC34064/D MC34064 MC33064 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 UNDERVOLTAGE designer an economical solution for low voltage detection with a single external resistor. The MC34064 features a trimmed-in-package bandgap SENSING CIRCUIT reference, and a comparator with precise thresholds and built-in hysteresis to prevent erratic reset operation. The open collector reset output is capable SEMICONDUCTOR of sinking in excess of 10 mA, and operation is guaranteed down to 1.0 V TECHNICAL DATA input with low standby current. These devices are packaged in 3-pin TO-226AA, 8-pin SO–8 and Micro–8 surface mount packages. A
