I finally made some search to better understand the meaning of the acronyms that I am used to read on the Vems documentation.
Please correct me if I am wrong
PFET
Probably not "Power MOSFET". I guess it is for "Positive channel MOSFET". These drive our Genboard output gates.
What puzzle me that these P gates are normally closed and, on the contrary, the genboard gates are normally open ??
There also have been a a topic for " Hi-Side PFET outputs " What are Hi-Side PFET ?
P259
Associated with the 6 current sources (eg. low current driver) of the genboard. It might be a chip with 6 outputs (channels) ??
