L6472PDTR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the VM pin is 45V, but it's recommended to keep it below 40V for reliable operation.
  • The current sense resistors (R Sense) should be chosen based on the maximum current rating of the motor and the desired current sense threshold. A good starting point is to use a 0.1 ohm resistor for a 2A motor and adjust from there.
  • The ENN pin is an active-low enable input that allows the user to enable or disable the device. When ENN is low, the device is enabled, and when ENN is high, the device is disabled. This pin can be used to shut down the device when not in use to reduce power consumption.
  • To configure the L6472PDTR for a unipolar stepper motor, connect the motor coils between the OUT1 and OUT2 pins, and the VM pin to the motor power supply. Set the DIR pin to control the motor direction, and use the STEP pin to control the motor stepping.
  • The maximum frequency of the STEP input signal is 100 kHz, but it's recommended to keep it below 50 kHz for reliable operation.
