Micropower Undervoltage Sensing Circuits with Programmable Output Delay

The MC33465 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. This device features a very low quiescent bias current of 1.0 μA 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.

MC33465 Features:

•Extremely Low Standby Current of 1.0 μA at Vin = 3.5 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)

•Programmable Output Delay by External Capacitor (100 ms typ. with 0.15 μF)

•Surface Mount Package (SOT±23 5±Pin)

•Convenient Tape and Reel (3000 per Reel)
