MAX6719UTRVD3+

Supervisors Overview

The MAX6719UTRVD3+ is a dual/triple ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two or three system power-supply voltages and asserts a reset signal if any monitored supply falls below its factory-trimmed threshold. The device maintains the reset state for a minimum timeout period after all supplies rise above their thresholds, ensuring system stability. It operates within a supply voltage range of 1.8V to 5V with a maximum operating voltage of 5.5V. The circuit features an active-low push-pull output, a 210ms reset delay, and consumes only 15µA of quiescent current. It is housed in a compact SOT-23-6 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Monitors multiple system power-supply voltages to assert reset signals upon undervoltage conditions
• Maintains reset for a defined timeout period after supply recovery to ensure stable operation
• Operates with ultra-low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Monitoring critical power rails in portable electronic devices
• Ensuring system reliability in embedded control circuits
• Providing power supervision for microprocessor-based systems

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm that the specific suffix matches the required pinout and electrical characteristics for your design. Check for RoHS compliance documentation as per regulatory requirements. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Supervisors Selection Notes

Select this component when monitoring two or three distinct voltage levels is required in a space-constrained design. Consider the fixed threshold voltages and the 210ms reset delay against system timing requirements. Evaluate the SOT-23-6 package size relative to available PCB real estate. Verify that the 15µA quiescent current aligns with power budget constraints for the target application environment.

Supervisors Part Context

This part belongs to the MAX6719 series of ultra-low-voltage supervisory circuits designed by Maxim Integrated. These devices are engineered to replace discrete components, reducing board space and improving reliability. The series includes variants with different threshold options and packages, catering to diverse power management needs in consumer and industrial electronics.

Supervisors Replacement Considerations

Check for direct replacements within the MAX6719 family with compatible thresholds and packages. Verify functional equivalence with other triple supervisor ICs if pinouts differ. Ensure substitute parts meet the same electrical specifications and environmental ratings.
