7.4.1 Power States

The TPS25752A can operate in one of three different power states: Active, Idle, or Sleep. The Modern Standby mode is a special case of the Idle mode. The functionality available in each state is summarized in Section 5.7. The device automatically transitions between the three power states based on the circuits that are active and required. See Figure 7-28. In the Sleep state, the TPS25752A detects a Type-C connection. Transitioning between the Active mode to Idle mode requires a period of time (T) without any of the following activity:

  • Incoming USB PD message
  • Change in CC status
  • GPIO input event
  • I2C transactions
  • Voltage alert
  • Fault alert
