MAX15091ETI+T

Hot Swap Controllers Overview

The MAX15091ETI+T is a hot-swap voltage controller designed for safe insertion and removal of circuit boards from live backplanes. It operates within an input voltage range of 2.7V to 18V and supports up to 9A of current. The device integrates a high-side N-channel MOSFET and provides precise current limiting with a current report output for monitoring. Packaged in a 28-TQFN (5x5mm) format, it ensures controlled power-up sequences and protects against overcurrent conditions during board insertion.

Hot Swap Controllers Feature Summary

• Integrates a high-side N-channel MOSFET for compact solution design
• Provides programmable current limiting with accurate current reporting
• Ensures controlled power-up sequencing to prevent bus collapse
• Supports safe hot-plugging operations on live backplanes

Hot Swap Controllers Applications

• Server and storage system backplane protection
• Telecommunications equipment hot-swap modules
• Industrial control board insertion systems
• High-reliability computing infrastructure power management

Hot Swap Controllers Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet to ensure compatibility with specific thermal and electrical requirements. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Cross-reference the part number with Analog Devices' discontinuation notices to avoid obsolescence risks during procurement planning.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring integrated hot-swap protection without external discrete MOSFETs. Ensure the application voltage does not exceed the 18V maximum rating. Consider the thermal performance of the 28-TQFN package relative to the expected load current. Verify that the current report output interface matches the monitoring system's input requirements for accurate fault detection.

Hot Swap Controllers Part Context

This device belongs to the Maxim Integrated hot-swap controller family, which focuses on protecting sensitive electronics during board insertion. It complements other PMIC solutions by handling the high-current transient events typical in modular server architectures. The integration of the driver and MOSFET simplifies PCB layout compared to discrete implementations.
