The MIC2588-2YM is suitable for a wide variety of hot-swappable applications such as telecom, industrial control systems, medical, automotive and network computing systems. Its excellent features make it ideal for applications that require power system resilience, efficient power delivery and multiple levels of fault protection.Microchip\'s MIC2588-2YM is designed to reduce the power overshoot and surge current associated with switching from off to on, while eliminating the need for an enabling FET or external MOSFET.

Working Principle

The MIC2588-2YM Hot Swap controller provides active current control and fault protection. It monitors the input voltage and output current, which enables it to detect the event and take appropriate action.When the load is first applied or during a brownout, the device limits the output current to the current threshold that corresponds to the output voltage. This allows the supply voltage to recover, preventing the output voltage from dropping below the UVLO threshold.During a fault condition, the output current is limited to a level that prevents it from exceeding the rated current of the system. The device then latches and sends an alert signal (ACTIVE_LOW_FAULT) to the controller, which can then take appropriate action. The device also provides a fault output (FAULT) which can be used to alert the system to a fault.

Conclusion

The MIC2588-2YM from Microchip Technology is an advanced hot swap controller that offers active current control and fault protection for a variety of hot-swappable applications. Its features make it ideal for applications that require high performance and reliability. The device monitors the input voltage and output current, allowing it to detect the event and take appropriate action.
