Driving P-Channel Mosfet

Simon:
If only we could do that in automotive, reading the fine print of TVS diodes and with the only protection from a surge being to ride it out 50+V parts for 12V and 100+V parts for 24V

--- End quote ---

The datasheet says RDS(on) of IRL6297 @120OC is 1.3x when ID is 8.5A. The ID of current design is between 0.65A and 1.0A.

Simon:
with 1A I would not even worry.
