Power Management Integrated Circuits (PMICs) are microchips used in all sorts of electronic devices. PMICs are tailored to meet specific application needs, such as linear and switch mode power supplies, high voltage power amplifiers, LED drivers, and many more. Hot Swap Controllers are one type of power management integrated circuit that is used when hot swapping devices. Hot swapping is the process of replacing a device while the power is still on. An example of a Hot Swap Controller is the ADM1278-2ACPZ.

The ADM1278-2ACPZ is a Hot Swap Controller manufactured by Monolithic Power Systems. It is designed for hot-swappable, industrial systems- and rackmount configurations. This Hot Swap Controller features Dual Hot Swap Outputs, High Accuracy +/-10mV Linear Regulation, and high speed overcurrent protection with accurate foldback current limiting. It also has adjustable inrush current limiting, short circuit protection and high isolation voltage between inputs and outputs.

The ADM1278-2ACPZ is designed for applications such as networking, consumer and enterprise systems, digital signage and medical devices. It can be used in forward and reverse topology systems and is suitable for DC to DC converters, which are used to regulate DC outputs from a low voltage input. This Hot Swap Controller is also suitable for high speed power inrush current limiters and active power factor correction (PFC) controllers. The Hot Swap Controller supports a wide range of operating temperature and package sizes, making it suitable for a variety of applications.

The ADM1278-2ACPZ is a single dual Hot Swap Controller that is ideal for Hot Swap applications. It provides seamless integration into a system level where hot swapping is required. The Hot Swap Controller features an integrated high-speed programmable bidirectional overcurrent limiting comparator with foldback current protection, allowing for dynamic adjustments to the foldback current limit level. The ADM1278-2ACPZ provides high voltage isolation between the input and output, allowing for a high degree of system protection.

The Hot Swap Controller also features an adjustable dead-time control that ensures a sleek transition between the in-rush state and steady-state mode. The in-rush current is adjustable, allowing for custom levels of in-rush current to be set, depending on the application. This Hot Swap Controller also features two independent outputs, providing greater flexibility and higher performance. The two outputs of the Hot Swap Controller can be used in parallel or independently.

The working principle of the ADM1278-2ACPZ Hot Swap controller is as follows: When power is applied to the circuit, the Hot Swap Controller senses the inrush current and begins to reduce it to the desired levels. The Hot Swap Controller features an adjustable current limit switch and adjustable inrush time coefficient. The current limit switch is adjusted to the desired protection level and the inrush time coefficient is adjusted to allow a smooth transition between the in-rush and steady-state current. The Hot Swap Controller provides high speed overcurrent protection with foldback current limiting and adjustable inrush current limiting.

The ADM1278-2ACPZ Hot Swap Controller is a reliable and cost-effective solution for providing hot swapping. It provides protection for industrial systems, rack mounts, forward and reverse topology systems, and DC to DC converters. The Hot Swap Controller provides adjustable inrush current limiting and foldback current protection, and is suitable for a wide range of operating temperatures and package sizes. The Hot Swap Controller features two independent outputs and adjustable dead time control, providing superior performance compared to other Hot Swap Controllers.
