I'm designing a circuit using an ST VN7020AJ high side driver. The application diagram recommends placing a diode from VCC to ground. The document doesn't provide any recommendations on the type of diode. The diagram, below, seems to suggest a Schottky diode, so I selected a BAT60J.
The board will be used in an automotive application and the load will vary with use and will at times be an inductive load. Sometimes it could be LED lighting, other times it might be a motor or mechanical solenoid.
Am I misreading this diagram, and should I be using a different diode? Also, is the diode necessary?
The document also doesn't say anything about Cext
