MAX6831YHUT+

Supervisors Overview

The MAX6831YHUT+ is a dual ultra-low-voltage microprocessor supervisor in an SOT-23-6 package. It monitors two voltage inputs with thresholds of 2.19 V and 2.313 V. The device features active low open-drain outputs, manual reset capability, and a watchdog timer. Operating from 2.0 V to 5.5 V, it maintains accuracy within 2.5% across temperatures from -40°C to +125°C. Quiescent current is 10 µA, and the reset delay is 320 ms.

Supervisors Feature Summary

• Dual-channel voltage supervision for independent monitoring of critical power rails
• Integrated manual reset input allowing user-initiated system resets
• Watchdog timer functionality to detect software malfunctions and trigger recovery
• Ultra-low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Portable electronic devices requiring reliable power management
• Embedded systems needing dual voltage rail supervision
• Industrial control units operating in extreme temperature environments

Supervisors Procurement Notes

Verify the exact suffix YHUT against the manufacturer's current datasheet to confirm pinout and threshold specifications. Confirm RoHS compliance status as listed in the official documentation. Check for obsolescence notices or lifecycle status updates directly from Analog Devices. Ensure the SOT-23-6 footprint matches your PCB design constraints before ordering.

Supervisors Selection Notes

Select this component when dual voltage monitoring is required in a compact SOT-23-6 package. It is suitable for applications demanding low standby current and precise threshold detection. Consider the fixed thresholds of 2.19 V and 2.313 V against your system's supply voltages. Verify that the 320 ms reset delay meets your system startup timing requirements.

Supervisors Part Context

The MAX6831 series belongs to Maxim Integrated's family of ultra-low-voltage supervisors. These devices are designed for microprocessor systems requiring reliable reset generation. The YHUT variant specifically denotes fixed thresholds and the SOT-23-6 surface-mount package. This series supports both manual reset and watchdog timer functions for robust system protection.

Supervisors Replacement Considerations

Cross-reference with MAX6831YFUT for similar dual-supervisor functionality. Verify compatibility with MAX6323BUT26+T if single-channel supervision suffices. Always validate electrical parameters and pinouts against the specific replacement datasheet.
