MAX6724UTLTD3+T

Supervisors Overview

The MAX6724UTLTD3+T is a triple ultra-low-power voltage supervisor in an SOT-23-6 package. It monitors three independent supply voltages with thresholds ranging from 1.8 V to 5 V and 900 mV to 3.3 V. The device features active low push-pull outputs, a watchdog timer, and a reset delay of 210 ms. Operating current is 15 uA, with a maximum supply voltage of 5.5 V. It functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Triple-channel voltage supervision for monitoring multiple power rails simultaneously
• Integrated watchdog timer for system reliability management
• Ultra-low quiescent current consumption for battery-powered applications
• Active low push-pull output configuration for direct logic interfacing

Supervisors Applications

• Portable electronic devices requiring multi-rail power monitoring
• Battery-operated systems needing extended operational life
• Embedded controllers requiring watchdog functionality
• Industrial control units operating in standard commercial temperature ranges

Supervisors Procurement Notes

Verify the specific suffix LT against official Analog Devices documentation to confirm threshold configurations and package details. Confirm RoHS compliance status through manufacturer datasheets. Check current lifecycle status as distribution availability varies by region and channel. Ensure compatibility with existing board layout constraints for the SOT-23-6 footprint.

Supervisors Selection Notes

Select this component when triple voltage monitoring is required alongside watchdog protection. Compare threshold ranges against target supply voltages to ensure proper triggering. Evaluate the 15 uA operating current against system power budgets. Verify that the 210 ms reset delay meets system startup timing requirements.

Supervisors Part Context

This part belongs to the MAX6724 series of triple supervisors from Maxim Integrated. It shares the SOT-23-6 form factor with other variants but differs in threshold settings and temperature grades. The series is designed for compact designs where space and power efficiency are critical constraints.

Supervisors Replacement Considerations

Check for MAX6724AUTLTD3+T if industrial temperature range (-40°C to +125°C) is required instead of the commercial grade. Verify pinout compatibility before substitution.
