ACS71020KMABTR-030B3-SPI Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for decoupling and place it close to the device.
  • Calibration involves applying a known current to the device and adjusting the offset and gain registers to achieve accurate measurements. Refer to the application note AN296065 for a step-by-step calibration procedure.
  • The maximum allowable voltage on the VCC pin is 5.5V. Exceeding this voltage may damage the device.
  • The ACS71020 has a built-in overcurrent detection feature. When an overcurrent condition is detected, the device sets the OCFAULT pin high. You can use this signal to trigger an interrupt or shut down the system to prevent damage.
  • Yes, the ACS71020 is compatible with 3.3V microcontrollers. The device's digital output is 3.3V-compatible, and the SPI interface can operate at 3.3V.
