PMIC – Hot Swap Controllers are regulators that are designed to protect against sudden, unexpected power failure and safeguard connected systems from potential damage. ADM1170-2AUJZ-RL7 is a Hot Swap Controller with a specialized features such as simple implementation of Hot Swap designs, Soft-Start with current limit, and fault status indicator.

Application Field and Working Principle

ADM1170-2AUJZ-RL7 can provide a safe power path to help systems move from one power source to another while keeping the load and system safe. The controller’s input range can support a wide range of input voltage, and it features an adjustable current limit and a precision voltage reference for maximum protection. The controller is designed for high efficiency and low power consumption, and it can work with both AC and DC power.

The ADM1170-2AUJZ-RL7 has two operating modes, Linear and Non-Linear. The Linear mode is for when the system is powered down and the load current drops below the threshold. In this mode the controller does not allow power to reach the load until a sufficient supply voltage is available. The Non-Linear mode is for when the system is powered up and the load current exceeds the threshold. In this mode the controller reduces the turn-on current by varying the output voltage in a linear fashion. This prevents overloading the system and keeps the load safe.

The ADM1170-2AUJZ-RL7 also features an adjustable soft-start circuit which limits the current rise during startup to prevent overloading the system. This is especially useful when the system has multiple outputs and different loads. The controller also features a precision voltage reference, enabling accurate turn-on and fault status indicators. These features help protect connected systems from possible damage due to sudden power failure.

The ADM1170-2AUJZ-RL7 Hot Swap Controller from ADI offers a reliable and cost-effective solution for Hot Swap designs. With its wide input range, adjustable current limit, and fault status indicator, the controller can protect against sudden power failure and maximize system uptime. The adjustable soft-start circuit and precision voltage reference ensure a smooth and safe startup which helps prevent system overload.
