DRV10970PWPR Frequently Asked Questions (FAQs)

  • A good PCB layout for the DRV10970PWPR involves keeping the high-current paths short and wide, using a solid ground plane, and placing the device close to the motor. TI provides a recommended PCB layout in the datasheet and application notes.
  • The sense resistor value depends on the motor current and the desired current sense accuracy. A smaller sense resistor value provides better accuracy but increases the power loss. TI provides a sense resistor calculation tool and guidelines in the datasheet.
  • The DRV10970PWPR has an operating temperature range of -40°C to 125°C. However, the device's performance and reliability may degrade at extreme temperatures. It's essential to ensure proper thermal management and heat sinking.
  • The DRV10970PWPR has built-in overvoltage protection (OVP) and undervoltage protection (UVP). However, additional external protection circuits may be necessary depending on the application. TI recommends using a voltage regulator and TVS diodes for added protection.
  • A 10uF to 22uF decoupling capacitor is recommended, placed as close as possible to the device's power pins. This helps to filter out noise and reduce electromagnetic interference (EMI).
