8.4 Device Functional Modes
8.4.1 Power States
The TPS25751A 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
6.7. The device automatically transitions between the three power states based on the circuits that are active
and required. See Figure 8-33. In the Sleep state, the TPS25751A 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
