MAX6354SYUK+T

Overview

The MAX6354SYUK+T is a dual-channel voltage supervisory circuit from the MAX6353L series, housed in an SOT-23-5 package. It monitors two input voltages with threshold levels of 3.08 V and 4.63 V, and over-voltage thresholds of 3.14 V and 4.72 V. The device features active-low push-pull outputs, a manual reset input, and a reset delay time of 180 ms. It operates within a supply voltage range up to 5.5 V, consumes 20 µA of supply current, and maintains an accuracy of 1.5%. The component functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel monitoring for multiple power-supply voltages
• Precision factory-set reset thresholds
• Active-low debounced manual-reset input

Applications

• Microprocessor system supervision
• Portable equipment power management
• Battery-operated systems

Procurement Notes

Verify availability status as this part may be subject to limited supply or discontinuation. Confirm that the ordering suffix corresponds to the specific voltage thresholds required for your design. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement plans.

Selection Notes

Select this component when dual-rail supervision is required without watchdog functionality. Compare against single-channel alternatives if only one rail needs monitoring. Consider the 20 µA quiescent current for battery-sensitive designs. Verify that the 180 ms reset delay meets system timing constraints.

Part Context

This device belongs to the MAX6351–MAX6360 family of microprocessor supervisors designed to improve system reliability. Unlike variants with watchdog timers or three-input monitoring, the MAX6354 focuses on dual-voltage supervision with manual reset capabilities. It shares the SOT-23-5 form factor common to this series.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX635x series. Verify that alternative parts match the 3.08 V and 4.63 V threshold specifications. Confirm package integrity and electrical characteristics align with original design requirements.
