MAX6351SVUT

Overview

The MAX6351SVUT is a dual voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.2V to 5.5V and features two low-active push-pull reset outputs referenced to VCC1 and VCC2 respectively. The device provides factory-precise power reset thresholds, a manual reset input with TTL/CMOS compatibility, and an extended operating temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power supply rails simultaneously for system reliability
• Provides precise factory-set power reset thresholds without external components
• Includes a debounced manual reset input compatible with standard logic levels

Applications

• Embedded systems requiring multi-voltage supervision
• Industrial control units with complex power architectures
• Communication equipment needing stable power monitoring

Procurement Notes

Verify the specific suffix code against official documentation to confirm threshold voltages and package variations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region and production cycle.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required. Ensure the application voltage falls within the 1.2V to 5.5V operational range. Consider the SOT-23-6 package constraints and thermal requirements for the intended environment.

Part Context

This part belongs to the MAX635x series of microprocessor supervisors designed for high reliability. These devices integrate watchdog timers and additional monitoring capabilities in other variants within the same family, offering a compact solution for power management in space-constrained designs.

Replacement Considerations

Check for MAX6351 variants with different suffixes for alternative threshold settings. Verify pinout compatibility if substituting with other dual-supervisor ICs from the same manufacturer.
