DRV8412DDW datasheet by Texas Instruments

DRV8412DDW 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 50V, but it's recommended to keep it below 40V for reliable operation.
• How do I configure the device for 3-phase or 2-phase operation?
  The DRV8412DDW can be configured for 3-phase or 2-phase operation by setting the PHASE pin high or low, respectively. For 3-phase operation, connect PHASE to VCC, and for 2-phase operation, connect PHASE to GND.
• What is the purpose of the EN pin, and how do I use it?
  The EN (enable) pin is used to enable or disable the device. When EN is high, the device is enabled, and when EN is low, the device is disabled. This pin can be used to shut down the device when not in use to reduce power consumption.
• How do I adjust the current sense gain?
  The current sense gain can be adjusted by connecting a resistor (Rgain) between the ISENSE pin and GND. The gain is calculated as Gain = 20/Rgain (kΩ).
• What is the purpose of the FLT pin, and how do I use it?
  The FLT (fault) pin is an open-drain output that indicates a fault condition, such as overcurrent or overtemperature. This pin can be connected to a microcontroller or other logic circuit to detect and respond to fault conditions.
