MAX6723UTSHD3

Supervisors Overview

The MAX6723UTSHD3+T is a triple ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8 V to 5 V and features three independent monitoring inputs with thresholds adjustable from 900 mV to 3.3 V. The device provides an active low, open-drain reset output with a fixed 280 ms reset delay time. It includes a watchdog timer function and consumes only 15 µA of quiescent current. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation across an industrial temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Triple input voltage supervision with independently adjustable threshold levels
• Integrated watchdog timer for system reliability monitoring
• Ultra-low power consumption suitable for battery-operated applications
• Active low open-drain reset output with defined delay timing

Supervisors Applications

• Portable electronic devices requiring multi-rail power management
• Industrial control systems operating in extreme temperatures
• Embedded microprocessor systems needing automated reset generation
• Battery-powered equipment prioritizing low standby current

Supervisors Procurement Notes

Verify the complete part number including suffixes such as +T or +TR against official Analog Devices documentation to ensure correct packaging and lead-free status. Confirm that the specific variant matches the required temperature grade and threshold specifications for your design. Cross-reference datasheet revision dates to ensure compatibility with current manufacturing standards.

Supervisors Selection Notes

Select this component when designing circuits requiring simultaneous monitoring of multiple voltage rails within a single compact footprint. Ensure the application demands the specific 280 ms reset delay and 15 µA current profile. Verify that the adjustable threshold range covers all critical supply voltages in the target system architecture without external resistor networks.

Supervisors Part Context

This device belongs to the MAX6723 family of ultra-low-voltage supervisors designed for microprocessor applications. It integrates multiple functions typically requiring separate components into a single six-pin package. The series is characterized by its ability to monitor complex power sequences while maintaining minimal power draw, making it distinct from standard single-channel supervisors.
