Introduction to ADM1275-3ARQZ-R7
The ADM1275-3ARQZ-R7 is Analog Devices’s high-performance, low-power, hot-swap controller. An important member of the Power Management Integrated Circuit (PMIC) family, the ADM1275-3ARQZ-R7 is designed for high current, hot-swap applications. It is commonly used in high-current systems with large-capacity power supplies, such as servers and storage systems, and is ideal for scenarios with multiple power supplies being hot-swapped in and out of operation.Features of ADM1275-3ARQZ-R7
The ADM1275-3ARQZ-R7 offers several features that make it particularly suited for high-current, hot-swap applications. It has an adjustable output voltage range of up to 5 V, which allows it to the support of multiple different power supplies. This can allow users to easily switch between different power supplies without needing to adjust the controller’s voltage range. Additionally, the controller’s low power consumption, small form factor, and wide operating temperature range of -40˚C to +125˚C make it suited for a variety of operation environments. The ADM1275-3ARQZ-R7 also has a built-in output power limiter which prevents damaging surges by limiting the output voltage and current.Application Field of ADM1275-3ARQZ-R7
The primary application field for the ADM1275-3ARQZ-R7 is high-current hot-swap applications, such as servers and storage systems. Using the hot-swap controller, multiple power supplies can be hot-swapped in and out of operation without requiring manual adjustment. This makes it well-suited for scenarios in which the power might need to be quickly changed, such as in data centers.The ADM1275-3ARQZ-R7 can also be paired with a hot-swap supervisor to provide additional protection against power surges caused by short circuits, overvolts, overtemps, and other issues. This adds an additional layer of protection for applications in which power surges could be particularly dangerous.Working Principle of ADM1275-3ARQZ-R7
The working principle of the ADM1275-3ARQZ-R7 is based on the hot-swap principle. When a power supply is plugged into the controller, it will automatically detect the voltage and switch on the power. The controller will then monitor the voltage and current of the power supply, and if either of these values exceeds the threshold set by the supervisor, the controller will shut off the power to the load. Once the voltage and current have returned to normal levels, the controller will then switch the power back on.The ADM1275-3ARQZ-R7 also features built-in protections against excessive voltage, current, and temperature. These protections act as a failsafe, ensuring that the current power supply is safely disconnected should any of the protection thresholds be exceeded. This ensures that the load is safely disconnected before any damage can be done to the load or power supply.Conclusion
The ADM1275-3ARQZ-R7 hot-swap controller is a powerful and reliable solution for high-current hot-swap applications. Its adjustable output voltage range, low power consumption, small form factor, and wide operating temperature range make it ideal for a variety of applications. Additionally, its built-in protections against excessive voltage, current, and temperature provide added safety for sensitive applications. All of these factors combined make the ADM1275-3ARQZ-R7 a perfect choice for any hot-swap application.The specific data is subject to PDF, and the above content is for reference
