MAX6351RVUT+

Overview

The MAX6351RVUT+ is a dual-channel multi-voltage supervisor IC from Maxim Integrated, housed in a compact SOT-23-6 surface-mount package. It monitors two independent voltage rails with specific thresholds of 1.58V and 2.93V. The device features an active-low reset output with a push-pull, totem-pole configuration. It ensures system reliability by providing a minimum reset timeout of 100ms following power-up or fault conditions. The component operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel supervision for monitoring multiple voltage rails simultaneously
• Active-low reset signal generation with defined timeout duration
• Push-pull output stage for robust drive capability
• Compact SOT-23-6 packaging for space-constrained designs

Applications

• Portable electronic devices requiring multi-rail power management
• Embedded systems needing precise voltage supervision
• Industrial control units operating in extended temperature ranges

Procurement Notes

Verify the complete part number including suffixes such as '+T' for tape-and-reel options when sourcing. Confirm that the supplier provides official datasheets matching the Analog Devices/Maxim Integrated specifications. Ensure the received components match the SOT-23-6 package marking and electrical characteristics defined in the public documentation to avoid counterfeit risks.

Selection Notes

Select this component when dual voltage monitoring is required in a small footprint. The fixed thresholds of 1.58V and 2.93V suit applications where these specific levels are critical. Consider the active-low reset polarity and 100ms timeout against system requirements. The SOT-23-6 package limits current drive compared to larger packages, so verify load compatibility.

Part Context

This device belongs to the MAX6351 series of multi-voltage supervisors. Variants like MAX6351TVUT+ or MAX6351TWUT+ share the same core functionality but differ in monitored voltage thresholds. The RVUT+ variant specifically targets the 1.58V and 2.93V threshold combination, distinguishing it from other series members with different monitoring parameters.

Replacement Considerations

Direct substitutes include other MAX6351 variants with adjusted thresholds if the 1.58V/2.93V values are not strict requirements. Cross-reference with similar dual-supervisor ICs from other manufacturers only if pinout and electrical specs align perfectly.
