Working Principle & Design

The ADM1813-10ART-REEL is designed as a combination of several complementary circuits, including a power control module, an array of power transistors, a timing circuit, and a host of logic circuits. The power control module utilizes a variable frequency oscillator, which is used to clock the outputs and control their active or inactive status. This allows for efficient control of power consumption in multiple independent domains.

The array of power transistors helps regulate the output voltage of each domain and can also enable hot-plugging of the power source. When the power source is connected, the device will measure the voltage and enable the output devices accordingly. This ensures that only devices which require the power will receive it, hence reducing waste and improving efficiency.

The timing circuit provides complete control of the active/inactive periods of each output, as well as the timing of their start and stop parameters, depending on the input voltage and the required output. The logic circuits in the device ensure the integration and synchronization of the different modules to ensure smooth operation.
