L6235QTR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the motor is 48V, as specified in the datasheet. However, it's recommended to derate the voltage to ensure reliable operation and to prevent overheating.
  • The sense resistor value depends on the desired current sensing range and the motor current. A general rule of thumb is to choose a sense resistor value that provides a voltage drop of around 0.5-1.5V at the maximum motor current. The datasheet provides a formula to calculate the sense resistor value based on the motor current and desired voltage drop.
  • The bootstrap capacitor is used to generate the high-side gate drive voltage. The recommended value is 10nF to 100nF, with a voltage rating of at least 50V. A larger capacitor value can provide a more stable gate drive voltage, but may increase the turn-on time.
  • To ensure SOA, follow the guidelines in the datasheet for thermal design, voltage derating, and current limiting. Also, make sure to monitor the device temperature and adjust the thermal design accordingly. The L6235QTR has built-in thermal protection, but it's still important to design for thermal safety margins.
  • A good PCB layout for the L6235QTR involves keeping the high-current paths short and wide, using a solid ground plane, and placing the sense resistor close to the device. The datasheet provides a recommended PCB layout and thermal design guidelines.
