L6470HTR Frequently Asked Questions (FAQs)

  • 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.
  • The value of R Sense should be chosen based on the maximum current rating of the motor and the desired current sense accuracy. A good starting point is to use a value between 0.1 ohm and 1 ohm, and then adjust based on the specific application requirements.
  • The ENN pin is an active-low enable input that allows the device to be enabled or disabled. 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.
  • The L6470HTR is a flexible device that can be configured for different motor types using the SPI interface. The device can be configured for stepper, DC, or brushless motor operation by setting the appropriate registers and configuration bits.
  • The maximum frequency of the PWM output is 100 kHz. The PWM frequency can be set using the PWM frequency selection bits in the configuration registers.
