The MAX5976BETE+ is a hot swap controller that is designed to deliver high performance hot swap protection for up to five power rails with individual current monitoring and current limiting. It provides a secure environment for critical power supplies to allow hot plugging without unintentional over-currenting.

The MAX5976BETE+ instantly turns off the power to each rail when it detects an over-current condition. This relieves the system of any danger due to excess current. It can also be configured to sound an alarm via a status pin if it experiences a current limit fault. Additionally, the MAX5976BETE+ includes protection against accidental short-circuits, reverse insertion and undervoltage, as well as an output voltage monitor for system supervision.

The MAX5976BETE+ is an ideal solution for hot plugging of PCIe-based storage drives into server systems with up to five power rails. Its high current limit handling capability of up to 500mA per rail coupled with fast response time of less than 100µs makes it well suited for hot swap applications that require fast current ramp-up and high dynamic current monitoring accuracy during hot plugging events.

A key benefit of the MAX5976BETE+ is that it offers additional features that are designed to make hot plugging easier and more reliable. Its clear over-temperature protection ensures that hot-plugged components don\'t melt due to overheating, while its auto-configuration feature allows the device to automatically configure the proper conditions for hot plugging. It also includes circuitry for monitoring the amount of current that each rail supplies, and if it exceeds a predetermined limit, the device will shut off the power to that rail.

The MAX5976BETE+ is a powerful and convenient way to enable hot plugging of PCIe-based storage drives into servers with multiple power rails. Its built-in protection functions and configurability options make it a reliable, cost-effective solution for critical hot swap applications. The device is available in a 16-pin, 2mm x 2mm DFN package, making it an ideal choice for tight space applications.
