ERROR pin example circuits ?

Chris,

We do not have any example circuitry that we can recommend to you.

As such we do not recommend to just have some passive circuitry to loop the Error pin into reset. Instead of that the Error pin should be monitored with some "intelligence". Some of our customers have used external ASICs or 8-bit micros as monitors.

TI is currently working on a companion chip for the TMS570 which will be able to monitor the Error pin with the said "intelligence".

Abhishek

Chris,

I split this thread to the forum responsible for the TMS570 companion chip to provide to some insight into the Error pin monitoring capability.

Abhishek

Hi, Thanks for letting me know, any chance you can add a link to the "companion chip" thread ? I tried some searches and could not find it.

Hi Chris,

I found this thread at http://e2e.ti.com/support/applications/automotive/f/26/t/107857.aspx.  It looks like Viktorija is planning to get you the datasheet on the TPS part.

All, the datasheet has been sent to Chris.

Viktorija

 Viktorija, can you send me the datasheet too?

 Thanks.
