Hello,

At TPS544B25, after Vin >= UVLO, how much time does a host have to wait before accessing I2C interface?

Best regards,

    Hi Hirano-san,

    Once both internal LDOs (BP3 and BP6) are up, the remaining timing before PMBus communication is enabled is typically about 60 µs. However, we recommend waiting 200 µs to account for variations.

    Thank you,
    Tomoya
