LMG1210: simulation issue

NITHYADAS P V

Part Number: LMG1210

I have simulated the lmg1210 in the pspice cadence. I am not able to get the results when i tried to use the ldo . I have to directly connect a 5 v to the ldo and input terminal to make it work. What should i do? I have already made the pcb . Please reply fast.

Hi Nithyadas,

Are you able to share a schematic of your setup? Also, are you able to run the simulation file successfully, or are you having errors? It looks like you will need VIN = 6V - 18V to use the internal LDO of the driver:

Please let me know if you are able to share the schematic.

Best,

sir,

I have simulated the same circuit. there was no error in running. I have give a input voltage of 10 V still no output comes as expected. Even the sample file given in the spice model when modified to use ldo is not working. I am not able to attach my pspice simulation file here.

Could u please tell me a method to share that so that this issue can be clarified?

Hi Nithyadas,

I just sent a friend request on E2E. After you've accepted you will be able to share the schematic/simulation file directly with me.

One potential fix for the simulation is to connect the HS_DAP pin to ground through a 1pF capacitor. Also, can you confirm if you are using TI PSPICE or Cadence PSPICE?

Best,
