MAX5900AAETT+T

Hot Swap Controllers Overview

The MAX5900AAETT+T is a hot-swap voltage controller designed for safe insertion of circuit cards into live backplanes. It operates from a negative supply ranging from -9V to -100V and supports a single channel. The device utilizes a TDFN-EP-6 surface-mount package and functions within an operating temperature range of -40°C to +85°C. It draws a maximum quiescent current of 500µA. The component provides inrush current limiting and overcurrent protection, requiring only an external N-channel MOSFET for implementation.

Hot Swap Controllers Feature Summary

• Enables safe hot-plugging of circuit cards into live backplanes without causing power-supply rail glitches
• Eliminates the need for most external components by integrating control logic with a single external N-channel MOSFET
• Provides adjustable inrush current limiting during startup to prevent voltage drops on the power bus
• Includes a circuit-breaker function for overcurrent protection after the initial startup phase

Hot Swap Controllers Applications

• Telecommunications equipment requiring safe module insertion
• Industrial control systems with modular architecture
• Data communication infrastructure involving live backplane connections

Hot Swap Controllers Procurement Notes

Verify availability status as this component may be discontinued or subject to limited supply constraints. Confirm that the specific suffix corresponds to the required package and thermal pad configuration. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Cross-reference the manufacturer's latest documentation for any product change notices affecting pinout or electrical characteristics.

Hot Swap Controllers Selection Notes

Select this controller when designing systems operating with negative voltages between -9V and -100V. It is suitable for applications requiring minimal external component count and simplified hot-swap functionality. Consider the TDFN-EP-6 package for compact board space requirements. Ensure the external MOSFET selected can handle the maximum expected load current and voltage ratings specified for the application environment.
