MAX4273ESE+

Hot Swap Controllers Overview

The MAX4273ESE+ is a single-channel hot-swap controller manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7V to 13.2V and draws a supply current of 600 µA. The device features integrated overvoltage protection (OVP) and undervoltage lockout (UVLO). It supports programmable functions including auto retry, circuit breaker, current limit, fault timeout, and latched fault modes. Designed for surface mount installation, it is housed in a 16-SOIC package with an operating temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Integrates startup current regulation and current glitch protection to eliminate external timing components
• Provides comprehensive protection via OVP, UVLO, and programmable fault handling mechanisms
• Supports auto-retry and latched fault modes for flexible system recovery strategies

Hot Swap Controllers Applications

• General purpose hot-swap circuit protection
• Backplane insertion systems requiring controlled power-up sequencing
• Server and storage chassis management interfaces

Hot Swap Controllers Procurement Notes

Verify the exact suffix against the manufacturer's official datasheet to confirm pinout and electrical specifications. Ensure the component meets RoHS3 compliance requirements if mandated by your design standards. Cross-reference the 16-SOIC package dimensions with your PCB footprint library to guarantee mechanical compatibility during assembly.

Hot Swap Controllers Selection Notes

Select this controller when internal switches are not required and external MOSFETs will handle the load current. Consider the 600 µA supply current for low-power standby applications. Evaluate the need for auto-retry versus latched fault behavior based on system reliability requirements and maintenance protocols.

Hot Swap Controllers Part Context

This component belongs to the MAX4271-73 family of hot-swap controllers. It shares functional similarities with other devices in the series but differs in specific packaging and minor parameter variations. The MAX4273 variant specifically targets general-purpose applications requiring robust protection without integrated switching elements.
