Maxim Integrated MAX5917AESE Hot-Swap Controller

The MAX5917AESE from Maxim Integrated is a sophisticated hot-swap controller designed to provide safe insertion and removal of circuit boards from live backplanes. This compact, single-channel device is housed in a 16-pin SOIC package and is engineered to manage the inrush current during plug-in, preventing glitches on the power supply line that can affect other system components.

One of the key features of the MAX5917AESE is its integrated electronic circuit breaker, which offers precise overcurrent protection by sensing the voltage drop across a sense resistor and responding to an overcurrent condition. The device ensures that the power-supply output remains stable and protected from the potentially damaging effects of overcurrent and short-circuit conditions.

The MAX5917AESE operates over a wide voltage range from 9V to 80V, making it suitable for a variety of applications including servers, storage systems, and network routers. Its adjustable overcurrent protection and programmable circuit breaker response time allow for flexibility in different system designs and requirements.

Additional features of this hot-swap controller include an active-low fault signal that notifies the system in the event of an overcurrent condition, under-voltage, or over-temperature condition. The undervoltage lockout (UVLO) ensures that the device operates only when the supply voltage is within an acceptable range. This enhances the reliability of the system by preventing operation under potentially damaging conditions.

The MAX5917AESE also offers a thermal shutdown feature that protects the device and the system from overheating. If the die temperature exceeds the thermal shutdown threshold, the device will automatically turn off, thus preventing thermal damage.

Overall, the Maxim Integrated MAX5917AESE hot-swap controller is a robust and reliable solution for managing power distribution in high-availability systems. Its comprehensive protection features and flexibility make it an ideal choice for designers looking to enhance the operational safety and longevity of their electronic systems.
