MAX20481CATEA/VY+

Supervisors Overview

The MAX20481CATEA/VY+ is a five-channel automotive system-on-chip (SOC) power monitor designed for supervising multiple voltage rails in complex electronic systems. It operates within an input supply range of 2.35V to 5.50V and draws only 150µA of operating current. The device features selectable threshold voltages including 500mV, 1.005V, 1.1V, 1.8V, 2.5V, and 3.3V, with high precision accuracy ranging from 102.5% to lower bounds as specified. Packaged in a compact LFCSP-16 or TQFN-16 form factor, it requires no external components for basic operation, making it suitable for space-constrained automotive applications.

Supervisors Feature Summary

• Five independent channel monitoring capabilities for comprehensive system supervision
• High precision voltage thresholds with selectable reference levels
• Low power consumption with 150µA operating current draw
• Compact surface-mount packaging requiring minimal external components

Supervisors Applications

• Automotive system-on-chip power management
• Multi-rail voltage supervision in vehicle electronics
• Battery management system monitoring
• Infotainment and instrument cluster power oversight

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors due to limited availability status. Confirm package variant matches design requirements as both LFCSP-16 and TQFN-16 options exist within the series. Check RoHS compliance documentation for environmental regulations. Ensure thermal dissipation calculations align with the 1.7978W power rating under worst-case conditions. Validate operating temperature range suitability for specific automotive zones.

Supervisors Selection Notes

Select this monitor when five distinct voltage rails require simultaneous supervision in automotive environments. Consider the 150µA quiescent current impact on battery life during standby modes. Evaluate the selectable threshold options against target rail voltages to ensure accurate fault detection. Verify that the 2.35V minimum operating voltage accommodates the lowest expected supply level. Assess package size constraints against available PCB real estate for the 16-pin configuration.

Supervisors Part Context

This component belongs to the MAX20481 series of automotive power monitors from Analog Devices/Maxim Integrated. It complements other devices like the MAX20479AATBF/VY+ which offers ASIL-B safety ratings but with different channel counts. The series targets modern automotive architectures requiring integrated supervision solutions without external discrete components.

Supervisors Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Cross-reference with MAX20479AATBF/VY+ for similar monitoring functions if channel count differences are acceptable. Verify pin compatibility before considering alternative packages within the same family.
