Hi David and Zach:

Please refer feedback from our end customer.

Please kindly let us know which points should be checked.

Looking forward your feedback.

1. We use embedded controller to control the OE timing, OE is rising after 1.1V about 20ms.

2. Customer has thermal pad connect to GND.

3. Please also refer their thermal tested results.the Tj of two TDP158 IC is around 62 degree C, which is much lower than the spec. 105 degree C.

Once the units are replaced, do we still have the same issue of no signal output?

Thanks
