MAX20481BATEA/VY+

Supervisors Overview

The MAX20481BATEA/VY+ is an automotive-grade power system monitor System-on-Chip (SoC) designed for high-reliability applications. It integrates seven voltage monitor inputs, including five fixed and two differential DVS tracking inputs with remote ground detection. The device features programmable over-voltage and under-voltage thresholds with ±1% accuracy. It includes a factory-programmable window watchdog and a low-active RESET pin configurable for various conditions. Operating within a -40°C to +125°C range, it utilizes a 3.0mm x 3.0mm side-wettable TQFN-16 package.

Supervisors Feature Summary

• Integrates seven voltage monitoring channels with independent remote ground detection for large current SoC power supplies
• Features a factory-programmable window watchdog with refresh and disable capabilities for system security
• Provides configurable low-active RESET output with factory-set threshold conditions
• Includes internal error-correcting code (ECC) on one-time programmable memory

Supervisors Applications

• Advanced Driver Assistance Systems (ADAS)
• Autonomous driving processing systems
• Remote sensor modules
• Power system monitoring and MCU/SoC supervision

Supervisors Procurement Notes

Verify the specific suffix 'BATEA' against official Analog Devices documentation to confirm exact factory programming configurations, as these parameters are unique to this variant. Ensure the component meets ASIL-B reliability requirements for your specific application context. Confirm the 16-SW-TQFN package dimensions match your PCB footprint design constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when a consolidated solution for multiple voltage rails is required to reduce bill of materials count. It is suitable for designs needing precise voltage supervision with programmable thresholds rather than fixed comparator ICs. Consider its ASIL-B capability if functional safety certification is mandatory. Evaluate the side-wettable lead package for enhanced thermal performance and solder joint inspection visibility in automated assembly processes.
