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 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.
