MAX5969BETE+T

Overview

The MAX5969BETE+T is a hot-swap voltage controller designed for safe insertion and removal of circuit boards from live backplanes. It operates within a supply voltage range of 2.7V to 18V and supports up to 7A of current. The device integrates an N-channel MOSFET driver and provides comprehensive protection features including overvoltage, undervoltage lockout, and programmable slew rate control. Packaged in a TQFN-16 format, it facilitates controlled power ramp-up during board insertion.

Feature Summary

• Integrates high-side N-channel MOSFET driver with built-in protection logic
• Supports controlled power-ramp sequencing via external capacitor programming
• Provides fault protection against overcurrent, overvoltage, and undervoltage conditions

Applications

• Telecommunications equipment backplane systems
• Industrial I/O modules requiring hot-swap capability
• Computing server blade insertion systems

Procurement Notes

Verify the specific suffix 'E' indicates the TQFN-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the 2.7V to 18V operating range. Check for any recent lifecycle notices or obsolescence warnings directly from Analog Devices. Validate thermal performance requirements for the selected enclosure.

Selection Notes

Select this component for applications requiring precise control over inrush current during board insertion. It is suitable for systems needing integrated fault protection without external discrete components. Consider the TQFN-16 package constraints for PCB layout. Evaluate if the 7A current limit aligns with load requirements. Verify interface compatibility with system monitoring protocols.
