Undervoltage Sensing Circuit
The MC34064 is an undervoltage sensing circuit specifically designed for
use as a reset controller in microprocessor-based systems. It offers the
designer an economical solution for low voltage detection with a single
external resistor. The MC34064 features a trimmed-in-package bandgap
reference, and a comparator with precise thresholds and built-in hysteresis
to prevent erratic reset operation. The open collector reset output is capable
of sinking in excess of 10 mA, and operation is guaranteed down to 1.0 V
input with low standby current. These devices are packaged in 3-pin
TO-226AA, 8-pin SO–8 and Micro–8 surface mount packages.
Applications include direct monitoring of the 5.0 V MPU/logic power
supply used in appliance, automotive, consumer and industrial equipment.
