Other Parts Discussed in Thread: TCAN1051-Q1

Hi,

Good day. I hope you are doing fine.

Our customer is using the SN65HVD1050A-Q1 and they want to know if they can left the Vref pin floating. Will it work?
I hope you could help us on this. Thank you.

Regards,

Cedrick

Cedrick,

Thanks for reaching out. The V_REF (aka "split") pin is an output, so leaving it floating should not inhibit the device's operation.

Has the customer considered the TCAN1051-Q1? While this is not an identical replacement to the SN65HVD1050A-Q1, it is a newer technology that has very similar operation with higher ESD, bus fault, and data rate. It is also ISO 7637 qualified for EMC, and it lacks the V_REF/SPLIT pin that the customer does not plan to implement (it is replaced with a no-connect).

Best,

Danny

Hi Danny,

Thank you for your answer.

Just to confirm, so they can use the SN65HVD1050A-Q1 without any problem while the Vref is floating. Right?

Cedrick,

The V_REF pin is an output that the designer is able to disregard if it is unwanted.

Best,

Danny
