Advance Information
Micropower Undervoltage
Sensing Circuits with
Programmable Output Delay
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.
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.
used in appliance, automotive, industrial and portable equipment.
