MAX17616AAFD+

Overview

The MAX17616AAFD+ is an 80V, 7A current limiter featuring a PMBus interface. It provides comprehensive protection including overvoltage, surge, undervoltage, reverse polarity, and loss of ground detection. The device operates with an input voltage range of 3V to 80V and delivers high-side current sensing with ±7% accuracy. It integrates an active-high output for load interruption.

Feature Summary

• Integrates PMBus interface for digital monitoring and control
• Provides multi-fault protection against overvoltage, surge, and reverse polarity
• Features high-side current sensing with specified accuracy

Applications

• Industrial equipment power management
• Automotive electronic systems
• Aerospace power distribution networks

Procurement Notes

Verify the specific suffix 'AFD+' against official Analog Devices documentation to confirm package type and temperature grade. Confirm that the component meets required automotive or industrial qualification standards if applicable. Ensure compatibility with existing PMBus controller logic levels before integration into the design.

Selection Notes

Select this component when an 80V input range and 7A continuous current handling are required. Choose based on the need for digital fault reporting via PMBus rather than analog outputs. Consider the TQFN package constraints and thermal requirements for the intended application environment.

Part Context

This part belongs to the MAX17616/A family of eFuse-like current limiters from Maxim Integrated. It serves as a robust power switch solution for protecting downstream loads in high-voltage environments. The series is designed for applications requiring precise current limiting and detailed fault status reporting.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic current limiters may lack the specific PMBus functionality or 80V rating.
