Introduction to Hot Swap Controllers Hot swap controllers are semiconductor components used to provide programmable voltage (or current) in order to ensure safe power up and power down of hot-swappable equipment. It is also responsible for preventing silicon level damage when hot swappable components are not present. This device is usually used in applications that have sensitive I/O lines or multiple boards which require safe insertion and removal of voltage supplies. This article will discuss the principles and applications of a specific hot swap controller, the MIC2587R-1BM-TR.

What is the MIC2587R-1BM-TR?The MIC2587R-1BM-TR is a P-channel MOSFET-based hot swap controller which is built for high powered applications. It is an over voltage protection (OVP) device that is part of the Over Voltage Protection (OVP) family. It offers superior ESD protection, a wide input-voltage range of 4.5V to 28V, and can sink up to 8A of current. This Hot Swap controller also features up to 8 programmable OVP levels, which can allow for optimized protection performance for many applications.

Working Principle: The MIC2587R-1BM-TR Hot Swap controller monitors the output voltage for over-voltage protection and uses two power MOSFETs to limit the current source when the load is absent. The controller also provides for an adjustable delay time for during insertion and removal of devices. In order to prevent overheating, the MIC2587R-1BM-TR also has an internal temperature compensation feature. This feature will automatically adjust the gate voltage of the power MOSFETs depending on the temperature. This helps to maintain high operational efficiency of the Hot Swap controller in high temperature environments. The MIC2587R-1BM-TR also contains a gate driver with a fast turn-on time, which helps to ensure efficient switching of the power MOSFETs.

Application Fields:Since the MIC2587R-1BM-TR provides superior over-voltage protection and ESD protection, it is typically used in hot-swap applications that require high power. Some of the most common application fields for this hot swap controller includes servers, networking equipment, servers, storage and telecommunications systems.The MIC2587R-1BM-TR can also be used in consumer application such as smart TVs, home automation systems, or automotive applications.

Conclusion: The MIC2587R-1BM-TR is a high powered Hot Swap controller that is specifically designed for hot-swap applications. It provides superior ESD protection and up to 8 programmable OVP levels, along with built-in temperature compensation, gate drivers, and adjustable delays. It is a versatile device that can be used in a wide variety of applications, including servers, networking equipment, storage and telecommunications systems, consumer applications, and automotive applications.
