MAX20480DATEZ/VY+

Supervisors Overview

The MAX20480DATEZ/VY+ is a seven-channel automotive system-on-chip (SoC) power-system monitor designed for ASIL-compliant applications. It supervises up to seven voltage rails with programmable overvoltage and undervoltage thresholds. The device operates within a supply voltage range of 2.35 V to 5.5 V and features an open-drain output configuration. It includes a fixed delay time of 32 ms for fault detection stability. Packaged in a 16-pin TQFN, it supports efficient monitoring of critical power domains in automotive environments.

Supervisors Feature Summary

• Provides comprehensive supervision for up to seven independent voltage inputs
• Features programmable overvoltage and undervoltage threshold settings for flexible configuration
• Designed to meet automotive functional safety compliance requirements
• Utilizes an open-drain output interface for reliable signal transmission

Supervisors Applications

• Automotive system-on-chip power management
• Multi-rail voltage supervision in vehicle electronics
• ASIL-compliant power monitoring systems

Supervisors Procurement Notes

Verify the exact suffix Z against the manufacturer's current product status, as availability may vary. Confirm that the DATEZ variant matches the required pinout and thermal specifications for your PCB layout. Ensure compatibility with the 2.35 V to 5.5 V operating range before integration. Cross-reference the open-drain output requirements with your microcontroller input capabilities.

Supervisors Selection Notes

Select this component when monitoring multiple voltage rails in an automotive SoC environment is required. It is suitable for designs needing ASIL compliance and programmable fault thresholds. Consider the 16-pin TQFN package constraints and the 32 ms delay characteristic for timing-sensitive applications. Ensure the supply voltage remains within the specified operational limits during all conditions.

Supervisors Part Context

This part belongs to the MAX20480 family of automotive power-system monitors from Analog Devices/Maxim Integrated. The family offers scalable channel counts, with this specific model supporting seven inputs. It is engineered for robust performance in harsh automotive electrical environments, providing essential protection and monitoring functions for critical system voltages.

Supervisors Replacement Considerations

Check for other variants within the MAX20480 family, such as those with fewer channels or different package options, if full seven-channel capability is not needed. Verify pin-to-pin compatibility with existing designs before substituting.
