  • POWER MANAGEMENT INTEGRATED CIRCUIT AND METHOD OF OPERATING POWER MANAGEMENT INTEGRATED CIRCUIT
    Publication number: 20260178097
    Abstract: A power management integrated circuit (PMIC) includes a dynamic voltage scaling (DVS) block configured to generate an output voltage signal, and a DVS monitoring block including a DVS monitoring code generator, and a safety monitoring unit configured to receive a DVS code and detect an error in the DVS code. The DVS block is configured to generate the output voltage signal based on the DVS code obtained by reflecting a DVS trim code in the DVS regulation code, and the DVS trim code is determined by a characteristic of a first digital-to-analog converter (DAC) included in the DVS block. The DVS monitoring code generator is configured to generate the DVS monitoring code obtained by reflecting a DVS monitoring trim code in the DVS regulation code, and the DVS monitoring trim code is determined by a characteristic of a second DAC included in the DVS monitoring block.
