DRV11873PWPR Frequently Asked Questions (FAQs)

  • A good PCB layout for the DRV11873PWPR 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 application note SLVA883.
  • 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 recommends using the DRV11873PWPR's internal sense amplifier and selecting a sense resistor value between 0.01 ohms and 0.1 ohms.
  • The DRV11873PWPR 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 to maintain a safe operating temperature.
  • The DRV11873PWPR has built-in overvoltage protection (OVP) and undervoltage protection (UVP) features. However, it's recommended to add external protection components, such as TVS diodes or zener diodes, to protect the device from voltage transients and spikes.
  • TI recommends using a decoupling capacitor with a value between 1 uF and 10 uF, depending on the application's noise sensitivity and power supply quality. A larger capacitor value can help reduce noise and improve the device's stability.
