| Order this document by MC33464/D MC33464 Advance Information 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 A 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.

Figure 5 provides a graph of time delays, for both rising and falling output waveform edges, as a function of CDelay. If another value of pullup resistance is used, the time delay can be calculated by using the equation: t + R CDelay Delay 1 V 1- th(MPU) V in ) tp where VthMPU is the microprocessor reset input threshold voltage and tp is the propagation delay internal to the MC33464.
