Maxim Integrated MAX5922AEUI+T Hot-Swap Controllers

The MAX5922AEUI+T from Maxim Integrated is a robust and versatile hot-swap controller designed to enable safe board insertion and removal from a live backplane. This component is part of the MAX5922A series and comes in a compact 28-pin TSSOP package, providing a space-efficient solution for power management tasks within a wide range of electronic applications.

Featuring integrated MOSFETs, the MAX5922AEUI+T offers a current limit and circuit breaker functionalities, which are essential for protecting both the device and the system from overcurrent conditions. It operates over a wide voltage range of 1V to 13.2V, making it suitable for low-voltage systems and ensuring compatibility with a variety of industry-standard voltages.

One of the key advantages of the MAX5922AEUI+T is its programmable overcurrent protection (OCP) feature. Users can set the current limit threshold according to their specific requirements, which provides design flexibility and enhances the protection of sensitive components. Additionally, the device includes a programmable circuit-breaker function that can be set to latch off, auto-retry, or be controlled by an external signal, offering further customization to the user's design.

The MAX5922AEUI+T also comes with an under-voltage lockout (UVLO) feature to ensure that the system operates only when the supply voltage is within an acceptable range, thereby preventing potential damage caused by low voltage conditions. Furthermore, the device supports a fault indicator output, which provides immediate feedback in the event of an overcurrent condition or thermal shutdown, enabling prompt system response to faults.

Maxim Integrated's commitment to reliability is evident in the MAX5922AEUI+T's built-in thermal protection. This safety feature prevents the device from overheating, thereby ensuring long-term stability and performance. With its combination of protection features and precise control, the MAX5922AEUI+T is an ideal choice for telecommunications, servers, networking, and other systems that require reliable power management.
