Maxim Integrated MAX5931LEEP+ Hot-Swap Controllers

The Maxim Integrated MAX5931LEEP+ is a sophisticated hot-swap controller designed to enhance the reliability and flexibility of high-availability systems. This device is engineered to allow safe board insertion and removal from a live backplane. By controlling the inrush current during plug-in, the MAX5931LEEP+ helps prevent damage to connectors, backplanes, and power supply components, thereby ensuring a seamless integration into the system.

With an operating voltage range of 0 to 16V, the MAX5931LEEP+ is suitable for a wide array of applications, including servers, storage systems, and network routers. The product is packed with features that provide precise control and monitoring to safeguard system integrity during hot-swap events. It offers programmable current-limit settings, which can be adjusted through external resistors, allowing designers to tailor the device to their specific needs.

The MAX5931LEEP+ also boasts an integrated charge pump that controls the external N-channel MOSFETs, eliminating the need for an external power source to drive the gates. This integrated feature simplifies the design and reduces the bill of materials. Additionally, the device comes with a built-in undervoltage lockout (UVLO) function, ensuring that the hot-swap action only occurs when the supply voltage is within an acceptable range.

For enhanced system diagnostics and protection, the MAX5931LEEP+ provides a fault output that signals when the device is in current limit or when the MOSFET is experiencing an overtemperature condition. This feature allows for immediate system response to potential issues, minimizing the risk of system failure. It also features a circuit-breaker function that latches off the MOSFET if the fault condition persists, offering another layer of protection.

Encased in a compact 20-pin QSOP package, the MAX5931LEEP+ is designed for space-constrained applications, providing robust hot-swap functionality without occupying excessive board space. Its reliability and comprehensive feature set make it an ideal choice for designing resilient and efficient hot-swappable systems.

With Maxim Integrated's commitment to quality, the MAX5931LEEP+ is a testament to their dedication to providing solutions that meet the rigorous demands of high-uptime environments.
