It provides protection and current limiting of the power circuit, including power transistors, voltage regulators, and other power management components. The ADM1175-2ARMZ-R7 is a versatile and well-suited hot swap controller for a variety of applications.

Application Fields

The ADM1175-2ARMZ-R7 is an ideal hot-swap controller for a wide range of applications, from medical instruments and industrial control systems to communications and transportation systems. Its high accuracy and flexibility make it the perfect choice for most critical applications that involve hot-swapping components for system power management.

The controller is suitable for hot-swapping loads, such as hard drives, optical transceivers, daughter cards, and other subsystems. It also works well with board-level system protection hardware such as circuit breakers, fuses, and current-limiting resistors. It can be used in both AC and DC applications, enabling it to manage components operating at variable or fixed voltages or with variable current draws.

The ADM1175-2ARMZ-R7 has wide application field, including industrial, communication and transportation applications. For instance, it is employed in the factory automation, where hot swapping of daughter cards, modules and other devices are required for power management. In the communication equipment, it provides protection for optical transceivers, thereby increasing system reliability. In transportation equipment, it can be used to protect sensitive power circuits from overloading and over voltage.

Working Principle

The ADM1175-2ARMZ-R7 is a safe and reliable hot swap controller. It works in two stages: current limiting and over-voltage protection. During the first stage, the controller provides current limiting for the power circuit. It monitors the load current in real-time and sets an upper limit on the current draw. It then turns off the power transistor once the limit is exceeded. This prevents the load from drawing an excessive current and damaging the circuit.

The second stage is over-voltage protection. This locks the power transistor if the voltage on the load side exceeds the over-voltage threshold. This protection prevents damage to the load due to excessive voltage. The ADM1175-2ARMZ-R7 also monitors temperature and provides a failsafe state if the temperature rises above the operating temperature range. This ensures that the controller is always in a known and safe state.

The ADM1175-2ARMZ-R7 has a number of characteristics which make it a great solution for hot-swapped systems. It has an adjustable current limit which allows for custom setups, allowing users to tailor the power protection to their exact requirements. It also offers over-voltage protection for increased safety and reliability, as well as temperature monitoring for additional preventive measures. It has an operating temperature range of -40°C to +125°C, meaning it is suited for industrial applications where components need to be hot-swapped in demanding conditions.

Conclusion

The ADM1175-2ARMZ-R7 hot swap controller is suited for a wide range of application fields including industrial, communication and transportation. It provides fast, safe and reliable power circuit protection, as well as temperature monitoring for added safety. Its adjustable current limit and over-voltage protection are also great benefits for custom-tailored power protection. The controller is an ideal solution for any hot-swapping system.
