MAX20484CATEC/VY+

Supervisors Overview

The MAX20484CATEC/VY+ is an automotive-grade power system monitor designed for ASIL-D safety integrity. It operates within a voltage range of 1.02V to 4.8V, utilizing a factory-set reset threshold for precise supervision. The device features active low and push-pull output options, ensuring compatibility with various logic interfaces. Qualified under AEC-Q100 standards, it supports an operating temperature range from -40°C to 125°C (TA). Packaged in a compact 16-SW-TQFN (3x3) surface-mount format with an exposed pad, it facilitates efficient thermal management and PCB space optimization in demanding automotive environments.

Supervisors Feature Summary

• Provides ASIL-D rated power system monitoring capabilities for high-safety applications
• Features factory-set reset thresholds for simplified design integration
• Offers flexible output configurations including active low and push-pull modes

Supervisors Applications

• Automotive engine control units requiring ASIL-D compliance
• Safety-critical power distribution systems
• Advanced driver assistance systems (ADAS) power monitoring

Supervisors Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against the official datasheet before ordering. Confirm that the factory-set threshold matches your system requirements, as these are not user-adjustable. Ensure the 16-SW-TQFN footprint aligns with your PCB layout constraints. Check current availability status as automotive components may experience supply fluctuations.

Supervisors Selection Notes

Select this component when ASIL-D functional safety certification is mandatory for the power monitoring circuit. The fixed threshold simplifies bill-of-materials management compared to programmable supervisors. Consider the 16-pin QFN package for its small footprint and thermal performance. Verify input voltage ranges cover the minimum and maximum operational voltages of the monitored rail.

Supervisors Part Context

This part belongs to the MAX20484 series of supervisory circuits from Analog Devices/Maxim Integrated. It is specifically engineered for automotive applications meeting stringent safety standards. The series includes variants like the MAX20480 and MAX20481, offering different pin counts or features while maintaining ASIL-D qualification. These devices complement other interface and power management solutions in complex automotive electronic architectures.

Supervisors Replacement Considerations

Direct substitutes include other ASIL-D qualified monitors from the same family, such as the MAX20480DATEC/VY+. Cross-reference pinouts and electrical characteristics carefully. Alternative suppliers must provide equivalent AEC-Q100 qualification and ASIL-D documentation. Verify that any replacement maintains the same output drive capability and reset timing specifications.
