A5984GETTR-T Frequently Asked Questions (FAQs)

  • Allegro provides a recommended PCB layout in the application note AN296065, which includes guidelines for thermal management, noise reduction, and signal integrity.
  • The maximum allowable motor current can be calculated using the formula: IMAX = (VDSS - VOUT) / (RDS(on) * 2), where VDSS is the drain-source voltage, VOUT is the output voltage, and RDS(on) is the on-state resistance.
  • The VREG pin is used to regulate the internal voltage of the device. It should be connected to a 10uF capacitor to ground to ensure stable operation.
  • The A5984GETTR-T has a built-in overcurrent protection feature. The device will automatically shut down if the current exceeds the threshold set by the OCx pins. The OCx pins can be connected to a resistor network to set the desired overcurrent threshold.
  • The recommended operating temperature range for the A5984GETTR-T is -20°C to 85°C. However, the device can operate up to 150°C with derating.
