Micropower Undervoltage Sensing Circuits with
Programmable Output Delay
MC33465N
T A = –30 to +80 C, Case 1212
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 A typical.
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.
