ACS780LLRTR-100U-T Frequently Asked Questions (FAQs)

  • A good PCB layout for the ACS780LLRTR-100U-T involves keeping the sense lines as short as possible, using a ground plane to reduce noise, and placing the device close to the current-carrying conductor. Allegro provides a recommended PCB layout in their application note AN296050.
  • Calibration of the ACS780LLRTR-100U-T involves applying a known current to the device and adjusting the output voltage to match the expected value. Allegro provides a calibration procedure in their application note AN296050.
  • The maximum allowable voltage on the VCC pin of the ACS780LLRTR-100U-T is 6.5V. Exceeding this voltage may damage the device.
  • The ACS780LLRTR-100U-T is rated for operation up to 150°C. However, the device's accuracy and linearity may degrade at high temperatures. Consult Allegro's application notes for guidance on using the device in high-temperature environments.
  • To protect the ACS780LLRTR-100U-T from EMI, use a shielded cable for the sense lines, keep the device away from high-current carrying conductors, and use a common-mode filter if necessary. Consult Allegro's application notes for more information.
