MAX4272ESA+

Hot Swap Controllers Overview

The MAX4272ESA+ is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.7 V to 13.2 V and features programmable current limiting for precise power-up control. The device incorporates power-fail detection capabilities and draws a typical operating supply current of 600 µA. Designed for surface-mount installation, it is housed in an SOIC-8 package and supports an industrial temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Provides controlled power-up sequencing through integrated current-limiting mechanisms
• Includes dedicated power-fail detection circuitry for system monitoring
• Features adjustable current limit settings for flexible load protection

Hot Swap Controllers Applications

• Hot swap applications requiring controlled insertion and removal of circuit boards
• Power distribution systems needing overcurrent protection during startup
• Industrial equipment requiring reliable power management in harsh environments

Hot Swap Controllers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific manufacturing lot dates prior to procurement. Ensure storage conditions meet specified requirements to maintain device integrity. Cross-reference datasheet revisions to confirm pinout and electrical characteristics match design specifications exactly.

Hot Swap Controllers Selection Notes

Select this component when designing circuits that require controlled power ramp-up and built-in current limiting for single-rail applications. Consider the SOIC-8 package constraints and thermal dissipation limits of 471 mW during layout. Evaluate the 600 µA quiescent current against system power budgets. Verify that the 2.7 V minimum operating voltage aligns with the target supply rail stability.
