DRV8832DGQ datasheet by Texas Instruments

DRV8832DGQ Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the VM pin?
  The maximum voltage that can be applied to the VM pin is 15V, but it's recommended to keep it below 12V for reliable operation.
• How do I choose the right sense resistor value for my application?
  The sense resistor value depends on the motor current and the desired current sense accuracy. A good starting point is to use the formula Rsense = 0.05 / Imax, where Imax is the maximum motor current.
• What is the purpose of the EN pin, and how do I use it?
  The EN pin is an active-high enable input that allows the device to be enabled or disabled. When EN is high, the device is enabled, and when EN is low, the device is disabled and the outputs are tri-stated.
• How do I configure the device for half-bridge or full-bridge operation?
  The DRV8832DGQ can be configured for half-bridge or full-bridge operation by connecting the appropriate pins. For half-bridge operation, connect the AIN1 and AIN2 pins together, and for full-bridge operation, connect the AIN1 and AIN2 pins to separate control signals.
• What is the maximum switching frequency that the DRV8832DGQ can handle?
  The DRV8832DGQ can handle switching frequencies up to 100 kHz, but the actual frequency limit depends on the specific application and motor characteristics.
