MC33465N-34ATR

Manufacturer Part Number
MC33465N-34ATR
Description
Micropower Undervoltage Sensing Circuits with Output Delay
Manufacturer
ON Semiconductor
Datasheet
MC33465
Micropower Undervoltage
Sensing Circuits with
Programmable Output Delay
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
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.
