MAX5903ACEUT+T

Hot Swap Controllers Overview

The MAX5903ACEUT+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 supports a single channel. The device features an adjustable current limit and includes power-fail detection capabilities. It functions in an ambient temperature range from -40°C to +85°C and is housed in a compact SOT-23-6 surface-mount package.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging into live backplanes without causing power-supply glitches
• Eliminates external components except the required external P-channel MOSFET
• Provides adjustable inrush current limiting and overcurrent protection

Hot Swap Controllers Applications

• Server and storage system backplane protection
• Telecommunications equipment power distribution
• Industrial control board insertion systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'ACEUT' against official Analog Devices documentation to confirm the exact package type and thermal rating. Confirm RoHS compliance status through the manufacturer's product compliance database. Ensure the ordering part number matches the intended pinout and functional variant, as suffixes define physical and electrical specifications.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring robust protection against inrush currents during module insertion. It is suitable for applications operating between +9V and +72V where minimizing external component count is critical. Verify that the external MOSFET selected can handle the maximum expected load current and voltage stress defined by the application requirements.

Hot Swap Controllers Part Context

This device belongs to the Simple Swapper family of hot-swap controllers from Maxim Integrated, now part of Analog Devices. These controllers are engineered to simplify power management in high-reliability environments by integrating essential protection logic into a small footprint, reducing design complexity compared to discrete solutions.

Hot Swap Controllers Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the MAX5902 or other variants within the MAX5903 series. Ensure any replacement maintains compatibility with the +9V to +72V input range and offers equivalent current limiting functionality.
