HOW TO CREATE OPTO COUPLER OR OPTO ISOLATER IN TINA

B J RAJENDRANATH

Hi,
i am doing a simulation in tina for voltage sensing ( optoisolators, optocouplers) of an induction machine can anyone help as i am new for this ie., which op-amp i have to select for voltage sensing here i am ataching the file the ckt to be connected but in the circuit the ic usec is acpl c87x but in tina iam not finding it in TINA so i want to design it can any help me ?2046.AV02-1289EN+DS+HCPL-7840+04May2011-EWV02.pdf 4011.Avago_ACPL-C87B_ACPL-C87A_ACPL-C870_Using Optical Isolation Amplifiers in Power Inverters for Vo.pdf

B J,

We do not make the device that you are trying to simulate. I would check with Avago (the manufacturer of the device) to see if there is any kind of Spice model support for the device. If the device does have PSpice model, it can be imported into TINA relatively easily.

I would also recommend you check out TI's line of capacitive based digital Isolators; www.ti.com/iso

You'll find that capacitive based isolation offers, lower power, higher reliability, as well as smaller packages to boot.

Hi Rajendra,

ACPL-C87AT spice model is available on Avago technologies web site. Follow the link below to download it.
