MICROPOWER UNDERVOLTAGE SENSING CIRCUITS

The MC341~ series are undervoltage sensing circuits specifi-

cally designed for use as reset controllers in portable micropro-

cessor based systems where extended battery life is required.

These devices offer the designer an economical solution for low

voltage detection with asingle external resistor.The M~4164

series features abandgap reference, acomparator with precise

thresholds and built-in-hysteresis to prevent erratic reset opera-

tion, an open collector reset output capable of sinking in excess

of 6.0 mA, and guaranteed operation down to 1.0 Vinput with

extremely low standby current. These devices are packaged in

3-pin TO-226AA and 8-pin surface mount packages.

Applications include direct monitoring of the 3.0 or 5.0 Volt

MPU/logic power supply used in appliance, automotive, con-

sumer, and industria( equipment.
