SN75471D Frequently Asked Questions (FAQs)

  • The SN75471D can handle a maximum current of 1A per channel, with a total current limit of 2A for all channels combined.
  • To protect the SN75471D from back-EMF, use a flyback diode (also known as a freewheeling diode) in parallel with the inductive load. This diode allows the current to continue flowing when the switch is turned off, preventing the back-EMF from damaging the IC.
  • The minimum input voltage required for the SN75471D to operate is 4.5V, although it's recommended to use a minimum of 5V for reliable operation.
  • Yes, the SN75471D can be used to drive a relay, but make sure to choose a relay with a coil voltage that matches the SN75471D's output voltage, and ensure the relay's coil current is within the SN75471D's current rating.
  • To reduce power dissipation, use a heat sink, ensure good airflow, and minimize the voltage drop across the IC by using a low-ESR capacitor and a low-resistance output stage.
