ATS685LSHTN-T Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the sense lines as short as possible and away from noise sources. Use a common mode filter or a ferrite bead to reduce EMI.
  • Calibration involves applying a known current to the device and adjusting the offset and gain registers to achieve accurate measurement. Refer to the application note AN296065 for detailed calibration procedures.
  • The maximum allowable voltage on the VCC pin is 5.5V. Exceeding this voltage may damage the device.
  • The ATS685LSHTN-T is rated for operation up to 150°C. However, the device's accuracy and reliability may degrade at high temperatures. Consult the datasheet for temperature-related specifications and derating factors.
  • Use a shielded cable for the sense lines, keep the device away from noise sources, and use a common mode filter or a ferrite bead to reduce EMI. Ensure the PCB layout is designed for EMC and follow the guidelines in the application note AN296065.
