MAX4273EEE Description

Short technical summary and product information.

The MAX4273EEE is an integrated hot swap controller from Analog Devices, part of the MAX4271/MAX4272/MAX4273 family. It enables the safe insertion and removal of circuit cards into live backplanes, preventing damage from inrush currents. This controller operates across a voltage range of 2.7V to 13.2V and has an absolute maximum rating of 15V for added protection.

 

Key features include startup current regulation, current glitch protection, and DualSpeed/BiLevel protection against short circuits and overcurrent conditions. The MAX4273 variant offers programmed fault recovery, along with features like Auto Retry, Circuit Breaker, Current Limit, and Fault Timeout. It has an operating current of 600µA and operates within a temperature range of -40°C to 85°C.

 

This device is available in a 16-QSOP package and a 16-SSOP (0.154", 3.90mm Width) package, both suitable for surface mounting. The MAX4273EEE is designed for general-purpose applications, reducing component count and design time with its integrated charge pump for external n-FET gate drive and an open-drain status output for fault indication.
