TC4420 and LEM HXS50NP

[Huby]

Hello.

I need to develop one small project where i have to use TC4420 and HXS50NP.

Those symbols are not in the multisim database. Does someone knows where i can find it or download it ?

If i have to create new symbols please tell me how to do this.

I need just for those two.

i forget to write that any alternative could also be ok.

Hi,

unfortunately, NI has no templates for TC4420 and HXS50NP. Maybe you find something on Google.

Best regards

Huby,

1. There is a manufacturer supplied model for the TC4420 on the Microchip site.

http://ww1.microchip.com/downloads/en/DeviceDoc/SPICE%20Models%20for%20TC4420-29%20MOSFET%20Driver%2...

Please attempt to create this part using this model and the tutorial - come back and reply if it doesn't appear to work (post a test circuit for others to benefit from if you get close).

Tutorial: http://www.ni.com/white-paper/3173/en

2. Also there does not appear to be a model for the LEM current transducer, however it may be relatively easy to mock up a simplified model using  a Current Controlled Voltage Source (or "H" source if familiar with SPICE syntax).  You can find that component here:

Master DB -> Sources -> CONTROLLED_VOLTAGE_SOURCES -> CURRENT_CONTROLLED_VOLTAGE_SOURCE

You could also look at the datasheet and enhance its functionality according to any functional block diagrams that may be included.

Regards,

Pat

Thank you for this model !

I implement this into symbol specifications and on first test i get this error messages:

SPICE Netlist Error in schematic RefDes 'u1', element 'g62': Unexpected ')' found in function ''
SPICE Netlist Error in schematic RefDes 'u1', element 'tc4420__tc4420__1': Due to errors, the component 'g62' has been omitted from the simulation

SPICE Netlist Error in schematic RefDes '', element 'aadcin1': Due to errors, the component 'aadcin1:xu1.4' has been omitted from the simulation
======= SPICE Netlist check completed, 8 error(s), 0 warning(s) =======

The pins are defined as folows:

1 - vdd

2 - input

3 - NC

4 - gnd

5 - gnd

6 - out

7 - out

8 - vdd

Any idea what this could be ?

Please include the circuit.

I think i found the error.

How to define "duplicated" pin names ?

I can not choose pin numbers ( as described in tutorial ).

All i can choose are the definitions that i create before.

There must be some step that i missed but i have no clue which one.

I created the same object 3 times and each time the same problem.

If you don't need a footprint you can go back to step 1 and create a simulation only (model only) part...

If you do need a footprint, in the symbol you can do 1 of 2 things. 

1. Create more than one symbol pin name with an underscore "_x" and map them to a unique footprint name.

2. Create a single symbol pin (ie 'gnd') and map this to multiple pins.

I took screen shoots of each step. This way it should be easy to follow.

Anyway... before i test it with circuit i try to run without and parts.

No luck, almost the same error.

If i make test with some other cmos component that is already in database, everything works OK

Any idea how to solve this ?

Is this some bug or something else ?
