TPS65982 Power Transition / Power Policy Description

What is the "System Power State" referred to in the Host Interface Manual and how is it related to the ACTIVE/IDLE/SLEEP states in the datasheet?  The datasheet discusses "Power Transition"s 1 - 4, but there's no mention of these in the Host Interface Manual.  In the datasheet, I2C responsiveness is a function of the power state, but "Sleep Configuration Register" documented in the Host Interface Manual, I2C responsiveness can be configured for any "System Power State".

It feels like both documents assumed this would be explained somewhere, but I can't find any documentation on the topic.  My confusion is further compounded by the changing terminology used across documents.

  • Hi Aaron,

    The different sleep states can be configured through register (0x20) "System Power State" The following values relate to the following sleep states in the device:

    0x00 = S0,
    0x03 = S3,
    0x04 = S4,
    0x05 = S5
    where;
    S0 = Sleep State Awake
    S3 = Sleep State Sleep Arm
    S4 = Sleep State Sleep Lite Ace
    S5 = Sleep State Sleep Deep Ace

    Thank you,
    Eric
