Part Number: HD3SS3220
My customer is evaluating HD3SS3220 used for USB interface of his system. He is now doing the USB Type-C Functional Test, but error message occurred like this.
1. TD 4.1.2 Unpowered CC Voltage Test
The PUT's CC voltage is not in vOPEN range.
2. TD 4.3.1 Sink Connect Source Test
The PUT does not start USB communication.
3. TD 4.3.4 Sink Connect Try.SNK DRP Test
The PUT does not continue to provide Rd on the CC pin for the duration of this test.
I am wondering if 1st problem was due to HD3SS3220's dead battery mode(datasheet pp.19). It sets the Rd as 5.1kohm so 1st test could not pass.
If so, can this operation mode be switched off?
And 2nd & 3rd problem were due to HD3SS3220's debug accessory mode(datasheet pp.23)? This mode is enabled by default, but the test requires debug accessory mode to be off. So the 2nd & 3rd test could not passed.
Is my consideration correct? Please let me know if there are any other possible causes.
Thank you and best regards,
Do you have the test report that I can review? I would like to confirm your explanation for the failures. TD 4.1.2 failure is most likely fails due to dead battery mode. TD 4.3.1 implies that TVS did no see USB enumeration process which can happen if TVS does not present termination, switch is not in correct position or USB Host is not ready to communicate. TD 4.3.4 may be caused by accessory mode support but should double confirm. Is accessory support marked in the VIF?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.
