Team,
Can you please help answer my customer's questions:
- Confirming D4 should be sized for a transient load current of 80mA, which would only occur during fault and for a short period as the gate is discharged. What is the required reverse voltage rating of the diode?
- Please confirm the purpose of Q3, D5, and R2. I saw in the datasheet it was mentioned they protect Q2 from VGS damage during reverse polarity, but I am having trouble visualizing the path that creates this issue.
