MAX6358RVUT-T

Overview

The MAX6358RVUT-T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent voltage rails, providing reset signals when inputs fall below specified thresholds. The device features an active low, open-drain output and includes a manual reset input with TTL/CMOS compatibility. It incorporates a watchdog timer for system reliability. The component operates within a supply voltage range of 1.2V to 5.5V and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Dual-channel voltage monitoring with factory-set threshold levels
• Integrated watchdog timer with defined startup and normal timeout periods
• Debounced manual reset input compatible with standard logic families
• Low power consumption suitable for battery-operated applications

Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Portable electronic devices utilizing multiple power domains
• Industrial control units needing reliable reset generation under fault conditions
• Communication equipment monitoring critical supply voltages

Procurement Notes

Verify the specific suffix configuration against current manufacturer documentation, as legacy part numbers may have discontinued status or limited availability. Confirm that the RVUT designation aligns with required threshold voltages and package specifications. Check for RoHS compliance details and ensure the source provides valid traceability for quality assurance purposes prior to procurement.

Selection Notes

Select this component when precise monitoring of two distinct voltage rails is required in a minimal footprint. Ensure the application demands an open-drain output structure and benefits from the integrated watchdog functionality. Verify that the operating temperature range meets environmental requirements and that the low quiescent current supports the system's power budget constraints effectively.

Part Context

This part belongs to the MAX635x series of multi-voltage supervisors designed for robust system management. These devices replace discrete components to improve accuracy and reduce board space. The series offers various threshold combinations and output configurations to suit diverse microprocessor architectures and power sequencing needs across industrial and consumer markets.

Replacement Considerations

Consult official cross-reference lists for direct substitutes. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure any alternative maintains the same package type and thermal characteristics to fit existing footprints without redesign.
