The TPS25810 monitors the • STD/1.5-A/3-A Capability Advertisement on CC Type-C Configuration Channel (CC) lines to determine when an USB device is attached. If an • Super Speed Polarity Determination Upstream Facing Port (UFP) device is attached, the • VBUS Application and Discharge TPS25810 applies power to VBUS and communicates • VCONN Application to Electronically Marked Cable the selectable VBUS current sourcing capability to the UFP via the passthrough CC line. If the UFP is • Audio and Debug Accessory Identification attached using an electronically marked cable, the • 0.7-µA (typ) IDDQ with No Attachment TPS25810 also applies VCONN power to the cable CC • Three Input Supply Options pin. The TPS25810 also identifies when Type-C – IN1: USB Charging Supply audio or debug accessories are attached. – IN2: VCONN Supply The TPS25810 draws less than 0.7 uA (typ) when no – AUX: Device Power Supply device is attached. Additional system power saving is achievable in S4/S5 system power states by using • Power Wake Supports Low Power in System the UFP output to disable the high power 5-V supply Hibernate (S4) and OFF (S5) Power States when no UFP is attached. In this mode the device is • 34-m Ω (typ) High-Side MOSFET capable of running from an auxiliary supply (AUX) • 1.7/3.4-A ILimit (±7.1%) - Programmable which can be a lower voltage supply (3.3 V), typically powering the system uC in low power states (S4/S5). • Port Power Management Enables Power Resource Optimization Across Multi-Ports The TPS25810 34-m Ω power switch has two selectable fixed current limits that align with the Type- • Package: 20-Pin WQFN (3 x 4) C current levels. The FAULT output signals when the • UL and CB Tests Underway switch is in an over current or over temperature condition.
