MAX6831SHUT

Supervisors Overview

The MAX6831SHUT+T is a dual ultra-low-voltage microprocessor supervisor manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent voltage rails with factory-set thresholds of 2.313V and 3.08V. The device features an active-low open-drain reset output, manual reset input, and a watchdog timer. It operates within a supply voltage range up to 5.5V and maintains accuracy within 2.5%. The reset delay time is 320ms, and the quiescent current is 10µA. It functions reliably from -40°C to +125°C in a compact SOT-23-6 package.

Supervisors Feature Summary

• Dual-channel voltage monitoring for independent power rails
• Integrated watchdog timer with startup delay for system protection
• Manual reset input capability for user-initiated system recovery
• Ultra-low quiescent current consumption for battery efficiency

Supervisors Applications

• Portable electronic devices requiring multi-rail supervision
• Battery-powered systems needing low standby current
• Microprocessor reset circuits in embedded applications
• Industrial control units operating in extended temperature ranges

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific suffix variations against official datasheets. Check lead times as availability may fluctuate. Ensure proper handling procedures for ESD-sensitive components during storage and assembly.

Supervisors Selection Notes

Select this component when dual voltage monitoring is required in space-constrained designs. Consider the fixed threshold voltages for compatibility with target power rails. Evaluate the SOT-23-6 footprint against PCB layout constraints. Compare quiescent current specifications against other supervisors if battery life is critical.

Supervisors Part Context

Part of the MAX683x family of ultra-low-voltage supervisors designed for portable electronics. Shares functional similarities with MAX6830 and MAX6835 but offers dual monitoring capabilities. Manufactured using CMOS technology for low power operation. Part of Maxim Integrated's portfolio now under Analog Devices.

Supervisors Replacement Considerations

MAX6830TZUT+T: Single channel variant with similar package and electrical characteristics. MAX6835VXSD4+T: Single channel alternative in SC70-6 package. Verify pinout compatibility and threshold voltage alignment before substitution.
