TAS5630 and OverCurrent limit

Hi TI,

sorry, missed the text. We are not sure how the TAS5630 will handle a transformer load when the transformer suddenly goes into saturation.Will the overcurrent limiter in TAS5630 protect the device from the shortcircuit that the transformer represents?

Will the "kick back" voltage when transformer goes out of saturation be a risk? The transformer is resistively loaded at secondary.

Thanks and regards

Trond,

The over-current protection will disable the outputs when the secondary is shorted. The internal diodes should be able to handle the resulting "kick back" voltage.

I know other customers have used these parts for driving transformers, but unfortunately, we have not studied this use case enough to offer many suggestions for you.
