PSPICE-FOR-TI: LMG5200　Inverting circuit

Part Number: PSPICE-FOR-TI
Other Parts Discussed in Thread: LMG5200

Please help someone. This is about the simulation of the LMG5200. The first image above is the circuit created by the LMG5200, and the second is the Hi and Lo inverting circuits I want to create. I'm done halfway, but the problem is with the connection of J5 in this second image.

1.25 PWLCSV.csv

I want to use the PWM source attached to this J5 connection. Could you tell me how to connect or connect diagram if I inserted it? Also, for PWM sources, you can follow the same connection as the J5 connector. The "top" of the PWM source corresponds to pin 4 of the J5 connector. The "bottom" of the PWM source corresponds to pin 1 of the J5 connector (ground). I've been told a little bit before, but I asked for help here because I don't know exactly how to connect. I have no date. So I want someone to cooperate. I will give you something, so thank you very much.

Hi Tosi,

We will have another member of our team contact you regarding this.

Best Regards,

Hi Tosi,

Could you please send a picture of your schematic?

Thanks,

Noah

Thanks for the reply.

The original schematic is here.　Don't worry about the first red frame

I want to analyze the connection between Hi and Lo in the original schematic. The connection was made, and the schematic that I made is in the third sheet.

I do not know the connection of the part of the red frame in the photograph of the schematic which I made in this schematic creation. Could you create a circuit and explain it based on these photos there? Also, please tell me how to do this because I want to place a PWM signal in J5.

Tosi.

Hi Tosi,

For V3, you will be connecting it as show in the LMG5200EVM schematic shown in the user's guide (https://www.ti.com/lit/ug/snvu551/snvu551.pdf?ts=1643211241238&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FLMG5200EVM-02). V3 will be connected between the top and bottom wires. The two in the middle can be removed or connected to ground.

This component should be left unconnected for use of a single PWM input. It will use the single input to create two complementary PWM outputs with a specific deadtime.

For the other three components with this symbol, pin 3 should be connected to 5V.

Thanks,

Noah

Thanks for the reply.

As you pointed out, we have made corrections to the red frame. Please confirm. I also placed GND where the 5V power supply was placed, but is this a mistake?
