Introduction to MIC2589R-2YM-TR Hot Swap Controllers

A hot swap controller is an electronic device that enables electronic boards or system cards to be hot-swapped or safely inserted and removed from a live system without interrupting its ongoing operation. The MIC2589R-2YM-TR hot swap controller from Microchip Technology Inc is a dual-channel hot swap controller optimized to efficiently and safely manage applications where one or more high power draws are needed.

Features of the MIC2589R-2YM-TR Hot Swap Controllers

The MIC2589R-2YM-TR hot swap controller is designed to meet the needs of application engineers for enhanced protection and monitoring for any system. It features and embedded control processor, dual MOSFET gate drivers and a PMBus / I2C serial interface. These features enable designers to customize system configurations with adjustable voltage rise and fall algorithms, power good timing and current limit settings. The high current DDR3/4 memory support in the MIC2589R-2YM-TR allows the controller to accept an external reference voltage of up to 13V.

Application Fields of the MIC2589R-2YM-TR Hot Swap Controllers

The MIC2589R-2YM-TR has broad application in various fields. It is ideal for switched power demand requirements in markets such as distributed power system, server, storage and networking systems. The controller is also well suited for powering high-efficiency low-power applications and low power standby systems, often found in consumer IoT products such as smart appliances, and also used in automotive and industrial applications.

Working Principle of the MIC2589R-2YM-TR Hot Swap Controllers

The MIC2589R-2YM-TR is a hot-swap controller based on voltage-mode control technology. It is designed to generate a gate drive voltage based on an internally generated current limit. This gate drive voltage is buffered and then amplified using separate power MOSFET gate drivers. Depending on the application, the MIC2589R-2YM-TR can protect against short-circuits as well as transitioning from normal operation to off mode in response to a supervisory event, such as an over-voltage fault.To prevent inrush current and prevent damage to the system, the MIC2589R-2YM-TR is designed with an adjustable soft start function which gradually rises the voltage from zero up to the configured voltage. This is done in a sequence of steps and takes the voltage from 0V to the final required voltage. The MIC2589R-2YM-TR also allows for advanced monitoring capabilities such as power good timing and current limit settings. This lets the controller monitor and detect any potential faults before they become dangerous. It also allows the controller to identify any power supply irregularities, like over or under voltage, or if the load current is exceeded. With these advanced monitoring capabilities, the system can be protected against potential power related issues, providing safety and security to your system.

Conclusion

The MIC2589R-2YM-TR hot swap controller from Microchip Technology Inc is a robust and versatile controller that is suitable for varied applications. Its dual channel design and embedded processing functions are optimized for efficient and safe management of high power draw applications. Its voltage-mode control technology protects against short-circuits, over-voltage and current limit settings. Also, adjustable soft start and power good timing offers advanced monitoring capabilities. The MIC2589R-2YM-TR is an ideal choice for any application that requires a reliable hot swap controller.
