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.
Trimmed-In-Package Temperature Compensated Reference
Comparator Threshold of 4.6 V at 25°C
Precise Comparator Thresholds Guaranteed Over Temperature
Comparator Hysteresis Prevents Erratic Reset
Reset Output Capable of Sinking in Excess of 10 mA
Internal Clamp Diode for Discharging Delay Capacitor
Guaranteed Reset Operation with 1.0 V Input
Low Standby Current
Economical TO–226AA, SO–8 and Micro–8 Surface Mount Packages
