Initially used to determinewhen an attach has occurred and what the orientation of the insertion is. Function-ality after attach depends on mode of operation as a host: Sets the allowable charging current for VBUS to be sensed by the attacheddevice Used to communicate with devices using USB BMC Power Delivery Used to detect when a detach has occurredOperating as a device: Indicates what the allowable sink current is from the attached host Used to communicate with devices using USB BMC Power DeliveryCC2I/OGNDG roundGroundVBUSP owerVBUS supply pin for attach and detach detection when operating as an upstreamfacing port (Device)POWER INTERFACEVDDP owerInput supply voltageLDOLDO V LDO OutputVCONNP ower SwitchRegulated input to be switched to correct CC pin as VCONN to power featured cables, powered accessories or dongles bridging Type C to othervideo or audio connectorsSIGNAL INTERFACESCL1/SDA2 (Note 1)

7 A different I2C address is used depending on which SDA and SCL are used and the state of ORIENT/I2C_ADDR at power up. Power Up, Initialization and Reset When power is first applied to VDD or VBUS, theFUSB307B goes through its POR sequence to load up all thedefault values in the register map, read all the fuses so thatthe trimmed values are available when VDD or VBUS is inits valid range. A software reset can be executed by writingSW_RES to 1 in RESET Register. This executes a full resetof the FUSB307B similar to POR where all the I2C registersgo to their default powered down, the FUSB307B is configured as aUFP with CC1 and CC2 have their respective Rdpull downs enabled such that a SOURCE can detect this asa UFP and turn on the FUSB307B device, power may become availablefrom VBUS when VDD is not present.

8 This state is stillconsidered Dead Battery until VDD is present. DuringDead Battery, the FUSB307B will continue presenting VDD is available, the TCPM can start the DRPtoggle by setting on theFUSB307B Battery Power up During a dead battery condition in a mobile application,the FUSB307B will be powered by VBUS and provide anLDO output to power a Controller or TCPM to establish aUSB PD FUSB307B will enable the Sink Path when attachedto a source with any advertised with more than one Type C port, the TCPM canenable or disable the appropriate sink VDD is greater than VDDGOOD, the internal LDO isbypassed and the device switches from VBUS to 5 demonstrates a dead battery power up sequencefor 5.
