MAX20480DATED/VY+

Supervisors Overview

The MAX20480 is a 7-channel automotive system monitor designed for SoC applications. It features low-voltage detection with open-drain outputs and integrated reset functionality. The device operates within a supply voltage range of 1.6V to 5.5V, ensuring reliable monitoring across various power rails. It includes a programmable watchdog timer and supports multiple threshold combinations for flexible configuration. Certified to AEC-Q100 standards, it functions reliably in temperatures from -40°C to +125°C.

Supervisors Feature Summary

• Provides comprehensive monitoring for seven distinct power rails simultaneously
• Integrates a watchdog timer to ensure system stability and fault recovery
• Features open-drain outputs compatible with various logic levels
• Supports configurable voltage thresholds for customized supervision requirements

Supervisors Applications

• Automotive System-on-Chip (SoC) power management
• Multi-rail voltage supervision in vehicle infotainment systems
• Safety-critical electronic control unit (ECU) monitoring
• Industrial controller power integrity verification

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm package type and temperature grade. Ensure compatibility with automotive qualification standards required for your specific application environment. Cross-reference pinouts carefully as variations may exist between similar family members.

Supervisors Selection Notes

Select this component when multi-channel supervision is required for complex embedded systems. Consider the open-drain output structure for interfacing with different logic families. Evaluate the need for integrated watchdog functionality versus external solutions based on system safety requirements and board space constraints.

Supervisors Part Context

This part belongs to the MAX204xx series of automotive-grade power supervisors. It complements other Maxim Integrated PMICs by providing dedicated monitoring capabilities rather than power conversion. The series targets high-reliability applications requiring robust fault detection and system reset management.

Supervisors Replacement Considerations

Check for direct cross-references within the MAX204xx family. Verify channel count and threshold configurations match exactly. Ensure any substitute maintains AEC-Q100 certification if used in automotive contexts.
