ADM00921

ADM00921 is a PAC1934 USB C POWERMETER which provides a high precision approach for measuring the power consumption over an USB Type-C bus. The on-board OLED display and navigation switch make it easy to swap between different measurement screens. It measures USB voltage and current, automatically calculates instantaneous power and accumulates power over time, making it suitable for power and energy monitoring. The voltage levels on CC pins are also measured. The power meter features a user-friendly joystick control and OLED display. PAC1934’s internal 48-bit power accumulator and 24-bit sample counter registers offloads the Power Meter MCU processing load, reducing the device power consumption. PAC1934’s internal high-speed data sampling rate (1024) ensures high accuracy metering data reporting with no MCU processing required. Up to 10 measurements can be saved in device FLASH memory. The device counters can be reset to 0 or can be restored to data saved previously in FLASH memory.
