MAX17613AATP+

Overview

The MAX17613AATP+ is a high-voltage current limiter and system protection device from the Olympus series, manufactured by Analog Devices Inc./Maxim Integrated. It integrates a low on-resistance FET with a typical RON of 130mΩ to manage power distribution in demanding environments. The component supports a wide input voltage range of 4.5V to 60V and handles negative input voltage faults up to -65V. It features programmable overcurrent protection ranging from 0.15A to 3A with ±3.5% accuracy. The device provides comprehensive protection against overvoltage, undervoltage, reverse current, and thermal overload conditions.

Feature Summary

• Integrates a robust FET with low on-resistance for efficient power switching and minimal conduction losses.
• Provides adjustable overvoltage lockout (OVLO) and undervoltage lockout (UVLO) thresholds via external resistors.
• Supports three programmable overcurrent response modes: auto-retry, continuous current limit, and latch-off.
• Blocks reverse current flow from output to input to prevent back-powering and system damage.

Applications

• Industrial automation systems including PLCs and control network modules
• Process instrumentation and sensor systems requiring reliable power management
• Weighing and metrology systems needing precise current limiting
• Battery-powered modules in harsh industrial environments

Procurement Notes

Verify the specific suffix 'A' in the part number MAX17613AATP+ to ensure compatibility with applications requiring reverse current blocking, as other variants like the MAX17613B allow bidirectional flow. Confirm that the 20-WFQFN exposed pad package matches your PCB footprint and thermal design requirements. Ensure that the external resistor values selected for setting OVLO and UVLO thresholds align with the specific voltage levels required by your system architecture to guarantee proper protection operation.

Selection Notes

Select the MAX17613AATP+ when system protection requires blocking reverse current in addition to standard overvoltage and undervoltage safeguards. This variant is suitable for applications where preventing back-flow is critical for safety or component integrity. Consider the 130mΩ typical on-resistance for efficiency calculations and verify that the 3A maximum programmable current limit meets the load requirements. The extended temperature range of -40°C to +125°C makes it appropriate for industrial-grade deployments.

Part Context

The MAX17613AATP+ belongs to Maxim Integrated's Olympus series, designed as compact and reliable integrated system protection solutions. These devices are engineered to reduce bill-of-materials count by integrating multiple protection functions into a single small-footprint package. The series aims to minimize board space while providing robust defense against electrical faults, making it a preferred choice for modern industrial and automotive electronics where reliability and size are paramount constraints.

Replacement Considerations

Direct substitutes within the same family include the MAX17613BATP+, which allows reverse current flow, and the MAX17613C, which focuses on reverse voltage protection. For broader system protection needs, consider alternatives such as the MAX14743, LTC4368, or MAX17525, ensuring that interface compatibility and protection thresholds match the original design specifications.
