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
μ
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.
MC33464 Features:
Extremely Low Standby Current of 0.8
μ
A at Vin = 1.5 V
Wide Input Voltage Range (0.7 V to 10 V)
Monitors Power Supply Voltages from 1.1 V to 5.0 V
High Accuracy Detector Threshold (
±
2.5%)
Two Reset Output Types (Open Drain or Complementary Drive)
Two Surface Mount Packages (SOT–89 or SOT–23 5–Pin)
