The LTC4231CMS-2#PBF is a state-of-the-art hot swap controller from Analog Devices Inc., designed to enable safe board insertion and removal from a live backplane. This integrated circuit is housed in a compact MSOP-10 package and operates over an input voltage range of 2.7V to 36V, making it versatile for a wide range of applications including servers, data centers, and telecommunications equipment.

Key Features

• Wide Operating Voltage Range: The device supports a broad range of input voltages from 2.7V to 36V, catering to various system requirements.
• Adjustable Current Limit: Users can set the current limit threshold via an external resistor, providing flexibility in different applications and protection levels.
• Gate Control for External N-Channel MOSFET: The LTC4231 controls an external N-channel MOSFET to gently power up capacitive loads, reducing inrush current and preventing system voltage droop.
• Overcurrent Protection: This feature helps prevent damage to the host system and the hot-swapped board in the event of a short circuit or excessive load.
• Power Good Output: A 'power good' status output indicates when the output voltage is within a specified range, ensuring stable operation before enabling the load.
• Undervoltage and Overvoltage Lockout: These protections ensure that the device operates only within the safe voltage range, enhancing system reliability.
• MSOP-10 Package: The compact package allows for a smaller footprint on the PCB, saving valuable board space.
