Command I2c 1ED3860MC12MXUMA1

[studiosipa]

I'm working with 1ED3860MC12MXUMA1 gate driver. 

I read the manual about the I2C command but without understand well. 

Is it possible to have or to receive a link where I can find information and examples about the I2C command. ??

The Gate driver doesn't work and I don't know why.... I need examples of code. I2c.

Thanks in advance

Dear GURU

first of all thanks for your feedback. But your code is not clear for me.

what is IC2Regs ?   it is not declared.

Coudl you explain me better ?  Sorry But i'm in trouble if I dont solve the problems. 

I cannot drive my Mosfet with this gate driver. Please help me.

Thanks again

Silvano

[studiosipa]

dear GURU,

just to explain you.  I have't problem with I2C with Texas, I have done this with directly IO drive. 

This Works. I have problem to determinate which command i have to send to the Gate in order to see in output the High and Low level.  When I drive the IN SIgnal in the ouput is alway low. (negative).

The output of the gate driver never go HIGH. 

Which comenad I have to send ?  which is the right sequence ?

I hope that this is clear. Thanks Again

Please give me an call. I have to understand the whole situation.

Before you can work with the X3-digital, you have to load the registers. After this the RDY-signal goes high, you can use the driver.
Please check it.

You can contact me any time.

Best regards

Many Thanks OLaf,

what do you mean with  the X3-digital ?  Do you mean SDA and SCL ?

More what do you mean with  "you have to load the registers"  Which registers ? all registers ? is that is not clear ?  

Which registers I have to load ?  All registers ?  

Could you explain me in more details with examples ?

Thanks lot.
