ALT80800KLPATR Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the device away from heat sources and ensure good airflow.
  • Use a low-impedance current sense resistor (CSR) and ensure the CSR is placed close to the device. Also, use a Kelvin connection to the CSR to minimize noise and ensure accurate sensing.
  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the input. This helps to filter out noise and ensure stable operation.
  • Use a TVS diode or a zener diode to clamp the input voltage. Also, consider adding a fuse or a PTC resettable fuse to protect against overcurrent conditions.
  • The recommended operating temperature range is -40°C to 125°C. However, the device can operate up to 150°C with derating.
