MAX6722UTZGD3

Supervisors Overview

The MAX6722UTZGD3 is a dual-channel uPower supervisor circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent voltage rails with fixed thresholds of 2.625V and 1.575V. The device features a manual reset input, an active-low push-pull output, and a watchdog timer. It operates within a supply voltage range up to 5.5V and consumes 15µA of quiescent current. The reset delay time is 210ms. It is housed in a SOT-23-6 package and functions between -40°C and +85°C.

Supervisors Feature Summary

• Dual-channel voltage supervision with fixed threshold levels
• Manual reset input capability for system control
• Integrated watchdog timer for fault detection
• Active-low push-pull output driver

Supervisors Applications

• Portable electronic devices requiring low power monitoring
• Battery-powered systems needing voltage supervision
• Embedded controllers requiring watchdog functionality
• Industrial equipment operating in extended temperature ranges

Supervisors Procurement Notes

Verify the specific suffix GD3 against the official datasheet to confirm pinout and electrical characteristics. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for obsolescence notices or lifecycle status updates from Analog Devices before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required alongside a manual reset function. The fixed thresholds eliminate the need for external resistor networks. Ensure the application requires a push-pull output rather than open-drain. Verify that the 15µA quiescent current meets the system's power budget constraints.

Supervisors Part Context

This part belongs to the MAX6722 series of uPower supervisors. It is designed for applications where space and power consumption are critical. The series offers various output types and threshold combinations. The MAX6722UTZGD3 specifically provides dual channels with a manual reset feature in a compact SOT-23-6 package.

Supervisors Replacement Considerations

Check for direct pin-to-pin replacements within the MAX6722 family with different suffixes. Verify if newer generations from Analog Devices offer equivalent functionality with improved specifications. Ensure any substitute maintains the same package type and electrical ratings.
