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−226AA, micro size TSOP−5, 8−pin  
SOIC−8 and Micro8surface mount packages. The NCV device is  
packaged in SOIC−8.  
Applications include direct monitoring of the 3.0 V or 5.0 V  
MPU/logic power supply used in appliance, automotive, consumer,  
and industrial equipment.
