ATM90E36A-AU-R Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a star topology for the power supply connections and keep the high-frequency components away from the analog circuitry.
  • Calibration involves adjusting the gain and offset of the current and voltage channels. Use the built-in calibration registers to adjust the gain and offset. You can also use the 'Auto-Calibration' feature, which uses an internal calibration source to adjust the gain and offset. Refer to the application note AN200043 for detailed calibration procedures.
  • Use a 3.3V or 5V microcontroller with a SPI or I2C interface. Ensure the microcontroller's clock speed is within the ATM90E36A-AU-R's specified range (up to 2 MHz for SPI and up to 400 kHz for I2C). Use a level shifter if the microcontroller's voltage is different from the ATM90E36A-AU-R's voltage.
  • The ATM90E36A-AU-R has several interrupt sources, including overcurrent, overvoltage, and energy measurement completion. Use the interrupt mask registers to enable or disable interrupts. Connect the interrupt pin to a microcontroller's interrupt input and handle the interrupt in the microcontroller's firmware.
  • The ATM90E36A-AU-R's typical power consumption is around 20 mA. To minimize power consumption, use the low-power mode, disable unnecessary features, and adjust the sampling rate and resolution according to your application's requirements.
