MAX4272ESA+T

Hot Swap Controllers Overview

The MAX4272ESA+T is a single-channel hot-swap voltage controller designed for safe insertion and removal of live circuit boards. It operates within a supply voltage range of 3V to 12V, with absolute maximum ratings extending to 13.2V. The device features programmable current limiting and includes power-fail detection capabilities. It draws a typical operating supply current of 600µA and functions reliably across an industrial temperature range from -40°C to +85°C. Packaged in an 8-lead SOIC surface-mount package, it dissipates up to 471mW of power.

Hot Swap Controllers Feature Summary

• Provides controlled power-up sequencing to prevent bus collapse during board insertion
• Features adjustable current limiting to protect against short circuits and overloads
• Includes integrated power-fail monitoring for system status indication

Hot Swap Controllers Applications

• Hot-pluggable peripheral cards
• Backplane systems requiring safe insertion
• Telecommunications equipment modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the supplier provides valid traceability data. Check for obsolescence notices as availability may be restricted. Validate that the component matches the exact pinout and electrical specifications required by the design.

Hot Swap Controllers Selection Notes

Select this controller for applications requiring precise control over inrush current during hot-swap events. Consider the programmable current limit settings to match load requirements. Evaluate the SOIC-8 package size against available PCB space. Verify compatibility with the system's voltage levels and thermal management constraints.
