PAC1934 USB A PowerMeter Part Number: ADM00974 Summary USB Type A Power and Energy Meter based on Microchip’s PAC1934. It measures USB voltage and current, automatically calculates instantaneous power and accumulates power over time, making it suitable for power and energy monitoring. It features PAC1934, a Quad DC Power/Energy Monitor with Accumulation IC. The power meter features a user-friendly joystick control and an OLED display, making it easy for everyone to use it. 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 and making room for additional high-level features. 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 the data saved previously in the FLASH memory. The power meter features a user-friendly joystick control Product Features • • • • • • • USB Type A Power Monitor Features PAC1934 Quad DC Power and Energy Accumulation Provides various information on: Bus voltage, current, instantaneous power consumption and energy accumulation Screen can be rotated 180 degrees to ease operation Can be used to profile power consumption on various USB-powered devices "Screen saver” feature further reduces the device internal power consumption, with no data or precision loss.
