PMIC (Power Management Integrated Circuit) systems, such as hot swap controllers, are integrated circuits that control and manage the power consumed by devices, such as microprocessors, which require very specific and substantial amounts of power. In some cases, a PMIC system may provide additional protection for the device it is powering.

The MIC2587-2YM-TR is a two−channel Hot Swap™ controller from MICROSEMI, providing protection and control for circuit boards and other applications that require a low-cost and efficient solution for device hot plugging. The controller offers an additional level of overcurrent protection with its built-in selectable current limit that limits fire safety-related catastrophic failures. The MIC2587-2YM-TR controller is an ideal solution for a variety of applications, including server, embedded systems, telecom racks, industrial equipment, consumer electronics, and consumer appliances, as it offers a relatively small footprint, a wide selection of overcurrent limit settings, and protection against short-circuit damage.

The application field of the MIC2587-2YM-TR hot swap controller is vast, covering a wide range varying from consumer electronics to server and industrial equipment. The low-cost system provides control of hot-plugging devices. It has the capability of providing both channel and rail-level power control and monitoring. The controller can detect and endorse hot-plugging, rail inrush current control, and the safe keep the device plugging in to the power rail. It\\'s also used for supply monitoring and power sequencing of circuits. It also encompasses other features such as controlling real-time power-consumption, reset/restart circuits, monitoring rail voltage status and implementing power-on/off control.

The working principle of the MIC2587-2YM-TR hot swap controller works in combination with the supply rail, which monitors the load current and rail voltage. In the power-on stage, the controller monitors the rail voltage and load current. If the voltage across the load increases, indicating an inrush current, the overcurrent-limit setting on the MIC2587-2YM-TR will set the voltage back to a safe level. In the meantime, the controller stores a record of the voltage and current information and sends it to the system. The controller will then adjust the current limit and keep the system within a safe operating range.

The MIC2587-2YM-TR hot swap controller can be enabled by two different pins, which allows either the output or the fault protection circuit to be enabled or disabled. When the controller is enabled, it monitors the supply rail, load current, and other parameters. If a fault occurs, the controller will then take appropriate action based on the situation. The controller can trigger a warning signal, shut down the system, or even reset the entire power-management system.

In short, the MIC2587-2YM-TR hot swap controller is an ideal solution for a variety of applications, offering a wide selection of overcurrent limit settings and protection against short-circuit damage. It provides overcurrent protection, rail inrush current control, and power-on/off control in a cost-effective and efficient manner. This versatile PMIC system can be used for a range of applications, from servers and embedded systems to consumer electronics, and can protect against catastrophic fire-related failures.
