MAX5903NNETT+T

Hot Swap Controllers Overview

The MAX5903NNETT+T is a hot-swap voltage controller designed for safe insertion of circuit cards into live backplanes. It operates within a supply voltage range of +9V to +72V and features an adjustable current limit function. The device provides overcurrent protection with a circuit-breaker capability and includes undervoltage lockout (UVLO). Packaged in a 6-TDFN (3x3 mm) surface-mount format, it supports an operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging into live backplanes without causing power-supply glitches
• Limits inrush current to the load during startup sequences
• Provides circuit-breaker functionality for overcurrent protection
• Eliminates need for external components except the P-channel MOSFET

Hot Swap Controllers Applications

• Server and storage backplane power sequencing
• Telecommunications equipment hot-swap modules
• Industrial control system card insertion
• High-voltage peripheral interface protection

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm package marking matches the 6-TDFN specification. Check RoHS compliance documentation for lead-free status. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering. Validate that the specific suffix corresponds to the TDFN variant rather than SOT-23.

Hot Swap Controllers Selection Notes

Select this controller when designing systems requiring protection against inrush currents during hot-swap operations. Ensure the external P-channel MOSFET ratings exceed the maximum supply voltage of 72V. Verify that the application requires the specific 6-TDFN footprint. Consider the adjustable current limit feature for matching load requirements. Confirm compatibility with the system's ground reference and control logic levels.

Hot Swap Controllers Part Context

This component belongs to the Simple Swapper family of hot-swap controllers from Maxim Integrated. It shares functional similarities with the MAX5902 but differs in packaging and specific pinout configurations. The series focuses on simplifying power management by minimizing external component count while providing robust protection against electrical faults during module insertion.
