MAX6717AUKSFD3+T

Supervisors Overview

The MAX6717AUKSFD3+T is a dual-input ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5 V and features a maximum operating voltage of 5.5 V. The device monitors two input channels with specific overvoltage thresholds of 1.08 V and 3 V. It provides an active low, open-drain reset output with a manual reset capability and a fixed reset delay time of 280 ms. The circuit draws a typical quiescent current of 15 uA and functions reliably across an extended temperature range from -40°C to +125°C. It is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Dual-channel voltage monitoring for independent power rail supervision
• Ultra-low quiescent current consumption suitable for battery-powered systems
• Manual reset input allows for controlled system initialization
• Extended industrial temperature rating for harsh environment operation

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems with multiple voltage domains
• Embedded computing platforms needing reliable reset sequencing
• Telecommunications equipment operating in extreme temperatures

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm exact threshold voltages match design requirements as variants exist within the series. Check RoHS compliance documentation for regulatory adherence. Ensure packaging specifications align with automated assembly processes. Validate lead times as stock levels may fluctuate significantly.

Supervisors Selection Notes

Select this component when dual voltage supervision is required in space-constrained designs. The SOT-23-5 package offers a small footprint compared to larger alternatives. Consider the 15 uA current draw for battery life optimization. Verify that the 280 ms reset delay meets system timing constraints. Ensure the open-drain output interface is compatible with the target logic family.

Supervisors Part Context

This part belongs to the MAX6717A series of ultra-low-voltage supervisors designed for microprocessor applications. It complements other Maxim Integrated PMIC solutions by providing dedicated reset functionality without complex configuration. The series supports various threshold combinations to accommodate different standard voltage rails commonly found in embedded systems.

Supervisors Replacement Considerations

Check for MAX6717AUKSVD3+T or MAX6717AUKZWD3+T if different threshold settings are acceptable. Verify pin compatibility before substitution. Review datasheet differences regarding reset delays and operating temperatures.
