MAX14691ATP+T

Overview

The MAX14691ATP+T is a high-voltage power limiter and hot-swap controller manufactured by Analog Devices Inc./Maxim Integrated. It supports an input supply voltage range of 5.5V to 58V and delivers up to 6A of output current. The device integrates overvoltage protection (OVP) and overcurrent protection (OCP) for robust system management. Operating temperatures span from -40°C to +125°C. It utilizes a 20-WQFN exposed pad surface-mount package, ensuring reliable performance in demanding industrial and automotive environments requiring precise power limiting.

Feature Summary

• Integrates overvoltage and overcurrent protection mechanisms for comprehensive circuit safeguarding
• Supports high-voltage operation with a wide supply range up to 58V
• Enables controlled hot-swap insertion to prevent bus transients during power-up

Applications

• High-voltage power distribution systems
• Hot-swap server and storage backplanes
• Industrial equipment power management

Procurement Notes

Verify the complete part number including the suffix 'T' for reel packaging configuration. Confirm the specific temperature grade matches application requirements. Ensure the 20-WQFN footprint aligns with PCB layout specifications. Cross-reference official datasheets for electrical characteristics before integration. Validate supplier authenticity through authorized channels.

Selection Notes

Select this component when high-voltage input handling up to 58V is required alongside precise current limiting capabilities. The integrated OVP and OCP features reduce external component count compared to discrete solutions. Consider the operating temperature range and thermal dissipation characteristics of the exposed pad package for heat management in dense layouts.

Part Context

This part belongs to the Maxim Integrated hot-swap and power management family, now under Analog Devices. It complements other PMICs by providing specialized high-voltage protection. The series focuses on protecting sensitive loads during insertion and fault conditions in industrial and communication infrastructure applications.

Replacement Considerations

Direct substitutes may include other Maxim/Analog Devices high-voltage power limiters with similar current ratings and protection features. Verify pin compatibility and electrical specifications against alternative models such as those within the same MAX146xx or MAX147xx families if available.
