A4986SESTR-T Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the A4986SESTR-T is -20°C to 85°C.
  • The current sense resistor value can be calculated using the formula: R Sense = 0.05 / (I OUT(max) x 0.1), where I OUT(max) is the maximum output current.
  • The VREG pin is used to connect an external voltage regulator to the device, allowing the user to regulate the internal voltage supply.
  • No, it is not recommended to use the A4986SESTR-T with a stepper motor that has a higher current rating than the device's maximum output current, as this can cause damage to the device.
  • The microstepping resolution can be adjusted by changing the logic levels on the MS1, MS2, and MS3 pins. Refer to the datasheet for the specific logic level combinations for each microstepping resolution.
