TMUX7219-Q1: Question about TMUX7219 applying to EVSE control pilot

Part Number: TMUX7219-Q1
Other Parts Discussed in Thread: TMUX7308F

Dear TI experts,

My customer considers TMUX7219-Q1 for their nest product.

I saw the document below in ;

Is it okay to cover IEC60364-4-41 SELV regulation when I apply TMUX7219-Q1 on EVSE control pilot?

the document show only the case of TMUX7308F. I need to confirm the case of applying TMUX7219-Q1.

Best regards,


  • Hello Chase,

    The case doesn't apply for the TMUX7219-Q1. For such application the device is required to have fault protection feature which the TMUX7219-Q1 doesn't have. 

    The TMUX7308F is well suited for this use case, but not the TMUX7219-Q1.
