LM74700D-Q1: LM74700D + CSD18511 -> valid? and short circuit protection

Tool/software:

hello,

i test the lm4700 and csd18511 for our configuration and design an prototype. everything works as excepted.

but this is my second try so i want to be sure that everything complied with.

We use the protection against battery short circuit, and it works :-)

i ve some notes:

• the CS18511 rds on is below the recommendation 
• voltages larger 20V i don't except
• i except no reverse voltage, that is not the main purpose here
• it is not necessary to protect the power supply against short circuit

I am wrong, or can i use the configuration?

Thanks

i ve attached an simplified schematic:
