Order this document by MC33464/D The MC33464 series are micropower undervoltage sensing circuits that are specifically designed for use with battery powered microprocessor based systems, where extended battery life is required. A choice of several threshold voltages from 0.9 V to 4.5 V are available. These devices feature a very low quiescent bias current of 0.8 µA typical. The MC33464 series features a highly accurate voltage reference, a comparator with precise thresholds and built–in hysteresis to prevent erratic reset operation, a choice of output configurations between open drain or complementary MOS, and guaranteed operation below 1.0 V with extremely low standby current. These devices are available in either SOT–89 3–pin or SOT–23 5–pin surface mount packages. Applications include direct monitoring of the MPU/logic power supply used in portable, appliance, automotive and industrial equipment.
