MC33465/D
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
μ
A 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.
Features:
Extremely Low Standby Current of 1.0
