A3985SLDTR-T Frequently Asked Questions (FAQs)

  • The maximum operating temperature range for the A3985SLDTR-T is -40°C to 150°C.
  • The A3985SLDTR-T requires a single 5V power supply, and it's recommended to use a decoupling capacitor of 10nF to 100nF between VCC and GND to ensure stable operation.
  • The maximum current rating for the A3985SLDTR-T is 2.5A, but it's recommended to derate the current based on the ambient temperature and PCB design.
  • The A3985SLDTR-T can be configured for half-bridge or full-bridge operation by connecting the appropriate pins and setting the input logic levels according to the datasheet.
  • The minimum input pulse width required for the A3985SLDTR-T is 100ns, but it's recommended to use a pulse width of at least 500ns for reliable operation.
