TMCS1101A4BQDR 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 decoupling capacitor (e.g., 10uF) close to the device to filter out noise.
  • Use a low-impedance current sense resistor (e.g., 1mΩ) and place it close to the device. Ensure the sense resistor is in the same thermal zone as the device. Use a Kelvin connection to the sense resistor to minimize errors.
  • The maximum allowed voltage on the VDD pin is 3.6V. Exceeding this voltage may damage the device. Ensure the power supply voltage is within the recommended range of 2.7V to 3.6V.
  • The device has a built-in thermal shutdown feature that activates when the junction temperature exceeds 150°C. Ensure proper heat sinking and airflow to prevent overheating. If thermal shutdown occurs, the device will recover automatically when the temperature drops below 140°C.
  • Use a low-pass filter (e.g., RC filter) with a cutoff frequency of around 100kHz to filter out high-frequency noise. The filter should be placed close to the device's input pins.
