Part Number: TPS43336-Q1
Please let me ask you a question about TPS43336Q1.
When an external clock outside specification frequency range is input to the SYNC pin, how does the TPS43336Q work?
For example, the external clock frequency of 400 kHz is input to the Sync pin usually. If the external clock frequency change to 40kHz or4MHz, how will the TPS43336Q work?
Best regards. Tsuyoshi Tokumoto
Hi Tsuyoshi Tokumoto,
We test our parts to operate within the given parameters in the datasheet. Hence, we cannot guarantee the performance and reliability of the part, when operating outside of those parameters. We do not recommend that you operate the part outside of specifications. If the part does not meet your performance needs maybe we can provide you with an alternative solution.
In reply to Raymundo Hernandez-Toscano:
Thank you very much for your prompt reply. I understand your opinion and suggestion.
However, please let me ask for you advice again.
As a background,my customer designs automotive products. He decides to use the TPS43336Q to next product.
From the viewpoint of FMEA,he wants to understand the behavior of TPS43336Q in the case of abnormal state.
Therefore, he wants to understand how it will work, if an external clock outside specification frequency range is input to the SYNC pin. (It is not a request that he wants us to guarantee it.)
From the above, could you please answer the following inquiry?
①Is there a possibility that the operation clock of the TPS43336Q switches between internal and external, even though a same frequency(for example,40kHz or 4MHz) external clock is input to the SYNC pin? ②Is there a possibility that the output voltage of the TPS43336Q goes to above and below from the range that the customer designed? ③Is there a tendency of behavior for low frequency(40kHz) and high frequency(4MHz)? Based on the above answers, he intends to design the system.
Best regards. Tsuyoshi Tokumoto
