TINA/Spice/SN65HVDA1040A-Q1: Spice MOdel

Part Number: SN65HVDA1040A-Q1
Other Parts Discussed in Thread: TINA-TI, , TCAN1042-Q1, SN65HVDA1040A

Tool/software: TINA-TI or Spice Models

Hello,

I am trying to create a spice model for some CAN transceiver, for example for the IC SN65HVDA1040A-Q1. My intention is to create a circuit at transistor level at least for the input and output circuits, as suggested in the datasheet.

Taking into account the equivalent circuit for the output pins (figure 15 in the datasheet) I would like to know the W/L of the MOS transistors and the MOS technology, for example L=100nm or 1um (or what else?). Furthermore it would be important to know the drop voltage of the diodes, optimally some values of the diode spice parameters.

Many thanks in advance for any feedback

Fererico,

Does it need to be the SN65HVDA1040A that you're modeling? We have a SPICE model for the TCAN1042-Q1, which is also an 8-pin CAN transceiver, in its product folder.

Regards,

Hello,

first many thanks for the feedback.

Of course, the product TCAN1042 could be OK for my application.
I will check the Spice Model with TINA (sorry, I need time because TINA cannot be installed at work) and after that I will contact you again.

Mainly I would prefer a Spice model with at least the input and output stages done by transistors, but if the subcircuit of TCAN1042 is really good realized maybe I won't need it

Regards,

Federico Travaglia

Hello,

fortunately I have found in Internet a very old Spice model with MOS transistors model for the driver/receiver.
Anyway many thanks for the support

Best regards
Federico
