A4982SLPTR-T Frequently Asked Questions (FAQs)

  • The A4982SLPTR-T can operate from -20°C to 85°C (TJ) and is suitable for automotive applications.
  • The R_sense value can be calculated using the formula: R_sense = 0.05 / (I_trip - I_run), where I_trip is the desired trip current and I_run is the running current.
  • The VREG pin is an internal voltage regulator output that can be used to power external circuitry, such as a microcontroller or other ICs.
  • To configure the A4982SLPTR-T for microstepping mode, connect the MS1 and MS2 pins to the desired logic level (GND or VCC) to select the microstepping resolution (full, half, quarter, or eighth step).
  • The A4982SLPTR-T has a maximum output current rating of 2A per phase, with a peak current rating of 3A per phase.
