PMIC (Power Management Integrated Circuit) – Hot Swap Controllers are used to protect valuable components in equipment when there is a power outage, or when the voltage or current gets too low. The ADM1075-2ACPZ-RL7 is a Hot Swap Controller which features a programmable over-current protection threshold, soft-start, adjustable ramp rates and an accurate peak current limit. In this article, we discuss the application field and working principle of the ADM1075-2ACPZ-RL7.

Application Field

The ADM1075-2ACPZ-RL7 is commonly used in the telecommunications, data center and network equipment fields. It is utilized in power draw protection for designs that need high-load current with transient, slow-start and fault protection. The applicability of the Hot Swap Controller extends from PDUs, Uninterruptible Power Supplies (UPS), RAID/Disk Arrays, and Battery Back-up systems to Network Routers and Enterprise Switches.

The Hot Swap Controller is ideal for applications requiring low power requirements such as PoE, PoE+, and 10/100BASE-T and Gigabit Ethernet. It is also applicable to hot-swap protection in enterprise equipment such as Storage Arrays, Rackmount Servers and Network Interface Cards. The Hot Swap Controller is suitable for powering multiple output supplies with transient, low-power, and fault-tolerant features.

Working Principle

The ADM1075-2ACPZ-RL7 Hot Swap Controller utilizes a programmable over-current protection threshold, soft-start, adjustable ramp rates and an accurate peak current limit. This allows it to provide a reliable surge protection and current limiting in the event of an overload condition. In addition, the Hot Swap Controller also has an internal voltage regulator, allowing it to maintain a stable power output throughout its range.

The Hot Swap Controller is able to sense the current levels present in the output and when the level rises above the programmed threshold, the controller is able to disconnect the output from the supply and protect both the input and the output from over current conditions. The controller is also able to automatically regulate the voltage by sensing the output\'s current levels. This ensures a steady and reliable power output.

The Hot Swap Controller can also perform thermal foldback, a feature which limits the power output based on the temperature of the output. This helps protect the components of the device from being damaged due to high temperatures. The Hot Swap Controller also has adjustable fault-reset timing which provides additional protection to the device. The Hot Swap Controller is also compatible with multiple power system architectures, making it an ideal choice for applications requiring high-current, transient, low-power, and fault-tolerant protection.

The ADM1075-2ACPZ-RL7 Hot Swap Controller is a versatile, cost-effective solution for a wide range of applications. Its programmable over-current protection threshold, adjustable ramp rates and accurate peak current limit provide reliable power draw protection. Its features make it a suitable choice for powering various equipment such as PDUs, UPSs, RAID/Disk Arrays, Network Routers and Enterprise Switches. Its compatibility with multiple architectures makes it a perfect choice for applications requiring high-load current with transient, slow-start, and fault protection.
