DESCRIPTION

· The MC34064 is an undervoltage sensing circuit designed for reset control in microprocessor-based systems.
· It provides an economical solution for low voltage detection using a single external resistor.
· Features include a trimmed-in-package bandgap reference and a comparator with precise thresholds and built-in hysteresis.
· The open collector reset output can sink over 10 mA and operates down to 1.0 V input with low standby current.
· Available in TO-92, TSOP-5, SOIC-8, and Micro8 packages.

FEATURES

· 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 over 10 mA.
· Internal clamp diode for discharging delay capacitor.
· Guaranteed reset operation with 1.0 V input.
· Low standby current.
· Pb-free and RoHS compliant.

APPLICATIONS

· Direct monitoring of 5.0 V MPU/logic power supply.
· Used in appliance, automotive, consumer, and industrial equipment.
· Suitable for applications requiring site and control changes with NCV prefix.
