The MIC2587R-2YM-TR is an advanced Hot Swap controller designed to prevent inrush current on any electronic system. It has a built-in high-side current-limited MOSFET and protects downstream load from voltage or current transients. The controller includes features such as over-voltage protection and input current monitoring, as well as a current sense resistor for LED stripe control. The device also features a unique automatic reset circuit which prevents the system from locking up due to an overloaded power supply.

The MIC2587R-2YM-TR has a wide operating voltage range from 2.7V to 20V and features 0.8V ±0.05% Reference Voltage accuracy. This makes the device ideal for a variety of power applications such as servers and enterprise storage, medical machinery, telecom, industrial automation, and consumer electronics. Other features include over-temperature protection, under-voltage lockout, fast-startup time, and low standby current. In addition, the device has programmable over-current and over-voltage protection limits.

The MIC2587R-2YM-TR is designed using a proprietary power-on reset circuit which uses an external capacitor to provide fast and accurate system initialization. The device also features an internal UVLO circuit that prevents the system from going into an unsafe state when the input voltage drops below a predetermined level. In addition, the device has an optional PRE/OUTP/UVLOT (pre-charge/output pull-up/under-voltage lockout) circuit for pre-starting the system.

The MIC2587R-2YM-TR is designed to provide a reliable way to prevent inrush current during the power-up of an electronic system or when replacing a defective component. This is achieved by monitoring the input voltage and gradually increasing the load voltage and current. The controller also features automatic reset, over-voltage protection, and other related features. The device is designed to be efficient and draw minimal power when in standby mode.

In terms of working principle, the MIC2587R-2YM-TR uses a built-in high-side current-limited MOSFET to protect downstream loads from voltage or current transients. The MOSFET is controlled by duty cycle and voltage feedback to provide an even current flow and prevent inrush current at start-up. Additionally, the device also utilizes a current sense resistor to monitor current and prevent the system from locking up due to an overloaded power supply. This ensures the device is able to automatically reset itself and regains normal operations quickly if an overload should occur.

Overall, the MIC2587R-2YM-TR Hot Swap controller is a reliable and efficient device ideal for a variety of power applications, from servers and storage, to industrial automation and medical machinery. Thanks to its built-in MOSFET and various protections, the device ensures reliable operation and prevents inrush current during system start-up. Furthermore, the device also has a low standby current and fast start-up times, making it an ideal choice for a variety of applications requiring power efficiency.
