A choice of several threshold voltages from 0.9 V to 4.5 V are available. This device features a very low quiescent bias current of 1.0 A typical. The MC33465 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, a time delayed output, which can be programmed by the system designer, and guaranteed operation below 1.0 V with extremely low standby current. This device is available in a SOT-23 5-pin surface mount package. Applications include direct monitoring of the MPU/logic power supply used in appliance, automotive, industrial and portable equipment.

Typical Complementary Output Application VDD 2 5 CD CD Input 1 Reset VDD Reset Gnd CPU MC33465 Series 3 Gnd APPLICATION CIRCUIT INFORMATION The MC33465 series are micropower undervoltage sensing circuits which offer a programmable time delayed output with the choice of either complementary output drive or open drain output configurations. Figure 14 shows the timing relationships between the input voltage and the resulting circuit waveforms. When the input voltage (Vin) exceeds the sense comparator threshold, the timing capacitor is allowed to charge through the internal delay resistor. When the output inverting driver threshold is exceeded, the Reset output switches from a logic "0" to a logic "1". The top curve of Figure 11 provides the nominal delay time for a given value of delay capacitance. When Vin drops below the comparator threshold minus hysteresis voltage, the delay capacitor discharges. When the capacitance voltage drops below the inverting drive threshold, the output switches from a logic "1" to a logic "0". The bottom curve in Figure 11 provides typical delay time for given delay capacitance values. The inverting driver threshold voltage is typically about Vin/2, as shown in Figure 10. 6 MOTOROLA ANALOG IC DEVICE DATA MC33465 Figure 14.
