A3980KLP-T Frequently Asked Questions (FAQs)

  • Allegro recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to minimize thermal resistance. A minimum of 2 oz copper thickness is recommended.
  • Use a robust PCB design with a secure component mounting, and consider adding a conformal coating to protect the device from moisture and contaminants. Additionally, ensure that the device is properly soldered and that the PCB is securely fastened to the system.
  • The maximum allowable voltage on the VCC pin during power-up is 16V. Exceeding this voltage may damage the device.
  • Yes, the A3980KLP-T can operate with a supply voltage as low as 3.3V. However, the device's performance and accuracy may be affected at lower supply voltages.
  • Check the output current sense resistor value, ensure proper PCB layout and routing, and verify that the device is properly powered and configured. Also, check for any external interference or noise that may be affecting the device's operation.
