MAX20484CATEC/VY+T

Supervisors Overview

The MAX20484CATEC/VY+T is an automotive-grade power system monitor designed for ASIL-D safety integrity. It integrates seven independent voltage supervision channels with a built-in watchdog timer and fault reporting capabilities. The device operates within a supply voltage range of 2.35 V to 5.5 V and supports industrial temperature ranges from -40°C to +125°C. Packaged in a compact TQFN-28 format, it provides comprehensive monitoring for complex multi-rail systems.

Supervisors Feature Summary

• Provides seven-channel simultaneous voltage supervision for critical power rails
• Achieves ASIL-D functional safety compliance through redundant architecture
• Integrates a configurable watchdog timer with timeout reset functionality
• Features dedicated fault output pins for immediate system alerting

Supervisors Applications

• Automotive central gateway modules requiring high reliability
• Advanced driver assistance systems (ADAS) power distribution units
• Infotainment system mainboard power management
• Body control modules with strict safety certification requirements

Supervisors Procurement Notes

Verify the specific suffix 'VY' against official Analog Devices documentation to confirm package variant accuracy. Confirm ASIL-D qualification status directly with the manufacturer or authorized distributors. Ensure the ordering part number matches the exact pinout and thermal pad configuration required by your PCB layout design.

Supervisors Selection Notes

Select this component when designing systems that mandate ASIL-D compliance for power monitoring functions. It is suitable for applications requiring multiple independent voltage checks without external logic gates. Consider the TQFN-28 footprint constraints during mechanical design. Evaluate if the integrated watchdog features meet the specific timing requirements of the target microcontroller.

Supervisors Part Context

This supervisory circuit belongs to the MAX204xx series of automotive power monitors. It complements other Maxim Integrated solutions like the MAX20479AATBF/VY+T, which offers similar monitoring but with ASIL-B certification. The series addresses the growing need for integrated safety monitoring in modern vehicle electronics architectures.

Supervisors Replacement Considerations

The MAX20479AATBF/VY+T serves as a potential alternative for less stringent ASIL-B requirements. Verify pin compatibility and channel count differences before substitution. No direct ASIL-D equivalent with identical pinouts is publicly confirmed.
