DRV10975ZRHFR Frequently Asked Questions (FAQs)

  • A good PCB layout for the DRV10975ZRHFR involves keeping the high-current paths short and wide, using a solid ground plane, and placing the device close to the motor. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
  • The sense resistor value depends on the motor current and the desired current sense accuracy. A good starting point is to choose a sense resistor value that results in a voltage drop of around 50-100 mV at the maximum motor current. The datasheet provides a formula to calculate the sense resistor value based on the motor current and desired sense accuracy.
  • The internal bootstrap diode is used to charge the high-side gate driver circuitry. It allows the high-side FET to be driven with a voltage higher than the input voltage, enabling the device to drive the motor with a voltage higher than the input voltage. The bootstrap diode has a minimal impact on device operation, but it's essential for proper device functionality.
  • The DRV10975ZRHFR has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. The resistor values can be calculated based on the desired overcurrent threshold and the sense resistor value. The device will shut down if the motor current exceeds the set threshold.
  • A ceramic capacitor with a value of 10-22 uF is recommended for the input capacitor. The capacitor should be placed close to the device and have a low ESR to minimize voltage ripple and ensure stable operation.
