The TPS25810 is a USB Type-C Downstream Facing Port (DFP) controller with an integrated 3-A rated USB power switch. The TPS25810 monitors the Type-C Configuration Channel (CC) lines to determine when an USB device is attached. If an Upstream Facing Port (UFP) device is attached, the TPS25810 applies power to V and communicates the selectable V current sourcing capability to the UFP via the passthrough CC line. If the UFP is attached using an electronically marked cable, the TPS25810 also applies V power to the cable CC pin. The TPS25810 also identifies when Type-C audio or debug accessories are attached. The TPS25810 draws less than 0.7 uA (typ) when no device is attached. Additional system power saving is achievable in S4/S5 system power states by using the output to disable the high power 5-V supply when no UFP is attached. In this mode the device is capable of running from an auxiliary supply (AUX) which can be a lower voltage supply (3.3 V), typically powering the system uC in low power states (S4/S5). The TPS25810 34-mΩ power switch has two selectable fixed current limits that align with the Type-C current levels. The output signals when the switch is in an over current or over temperature condition. The output controls power management to multiple high current Type-C ports in an environment where all ports cannot simultaneously provide high current (3 A).
