Hello,

I am using TPS659037 PMIC to power up AM5728. As you see picture below, the time interval is 550us. Is the time of RESET_OUT programmable? If yes, which register should I program. Thanks.

    Jeff,

    Hi, welcome to E2E! The power sequence cannot be changed by software. The power sequence for TPS659037 is defined by OTP and is fixed once it leaves the TI factory.

    Please let me know if you have further questions.

    Thanks,
    Nastasha
