MC33464 Micropower Undervoltage Sensing Circuits
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 ตA typical. The MC33464 series features a highly accurate voltage reference, a comparator with precise thresholds and builtญin 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 SOTญ89 3ญpin or SOTญ23 5ญpin surface mount packages. Applications include direct monitoring of the MPU/logic power supply used in portable, appliance, automotive and industrial equipment.
