Micropower Undervoltage

Sensing Circuits

The MC34164 series are undervoltage sensing circuits specifically

designed for use as reset controllers in portable microprocessor based

systems where extended battery life is required. These devices offer

the designer an economical solution for low voltage detection with a

single external resistor. The MC34164 series features a bandgap

reference, a comparator with precise thresholds and built−in hysteresis

to prevent erratic reset operation, an open collector reset output

capable of sinking in excess of 6.0 mA, and guaranteed operation

down to 1.0 V input with extremely low standby current. The MC

devices are packaged in 3−pin TO−92 (TO−226AA), micro size

TSOP−5, 8−pin SOIC−8 and Micro8™ surface mount packages. The

NCV device is packaged in SOIC−8.
