Hi TI expert,

A question here, that how can the OTP programmed for the first time?

For a project, when the TPS659037 is onto the board, how should the voltages and sequence information programmed into the OTP? should I using external COU to programmed the TPS659037 first?

Before the TPS659037 programmed, the TPS659037 could not drive the AM572X correctly, right?

BR,

Hello,

The TPS659037 OTP is pre-programmed. Once the device is powered up, the output resources start with a defined power up sequence. You can change the resources after the power up sequence is complete through the I2C communication. There are many OTPs and you can choose the right OTP according to the system demand. I hope this answers your question and please let me know for further support.

Regards
