Description of the problem

In a project testing OSN1500, the TPS reversal was abnormal when the branch board was pulled out of the working board immediately after the TPS protection was configured. After replacing the main control board and reconfiguring it, it is still invalid.

Processing

summarize

root cause

After the TPS protection configuration is completed, the host, the single board and the protocol module need to handshake to confirm the current state of the TPS protection group, which generally takes 2 minutes to reach stability; in the case where the protocol state is not stabilized, the inversion test is conducted, leading to inversion anomalies.
