A PMIC (Power Management IC) is a type of integrated circuit that is used to regulate and control the flow of power in a wide variety of applications. Hot swap controllers, also known as hot-swap applications, are among the many types of PMICs available. The MCP18480T-I/SS is a very common type of hot swap controller that is used by many different manufacturers and industries. In this article, we will go over the application field and working principle of the MCP18480T-I/SS.

Application Field of MCP18480T-I/SS

The MCP18480T-I/SS is a high voltage, surface mountable, high power hot swap controller designed for brushless DC motor and sensor applications. It is used to control the start and stop of DC motors, as well as their operating speed. It is optimized for space-saving and robust operation, and its features include high efficiency, low noise and complies with several international safety standards for low-voltage applications.

The MCP18480T-I/SS is often used in industrial automation, robotics, HVAC systems, and a range of other applications. It is suitable for gimbal motors, vending machines, and other applications where efficiency and low noise are required. Additionally, it is often used in automotive motor controllers and other vehicle systems.

Working Principle of MCP18480T-I/SS

The MCP18480T-I/SS draws its power from a high voltage DC source, such as a battery. The high voltage DC is converted to a constant lower voltage, which is then regulated to provide the optimal power supply for the motor or sensor being used. To reduce inrush current and start-up times, a pre-biased circuit is used to control the start-up of the motor or sensor. The pre-biased circuit is enabled through digital logic signals.

The MCP18480T-I/SS also features a current sensing circuit designed to protect the motor or sensor from current overloads. The current sensing circuit is triggered when the current surpasses a predetermined level. An over-current alert signal is sent to the system in order to prevent damage to the motor or sensor. In addition, an under-voltage lockout feature is also included to prevent the system from operating at an unsafe voltage level.

Finally, the MCP18480T-I/SS also has low-side current measurement capabilities. This feature is used to measure the amount of power that is consumed by the motor or sensor, allowing for better energy management and efficiency.

Conclusion

The MCP18480T-I/SS is a powerful, feature-rich hot swap controller that is often used in industrial automation, robotics, HVAC systems, and other applications. Its features include high efficiency, low noise, current sensing, and overload protection. In addition, it has low-side current measurement capabilities for improved efficiency and energy management. With its wide range of features, the MCP18480T-I/SS is a great choice for many different applications.
