TPS25810 USB Type-C® Interface Evaluation Board

The TPS25810A-Q1 device is a USB Type-C downstream-facing port (DFP) controller with an integrated 3-A rated USB power switch. The device monitors the Type-C configuration channel (CC) lines to determine when a USB device is attached. If an upstream-facing port (UFP) device is attached, it applies power to VBUSand communicate the selectable VBUScurrent-sourcing capability to the UFP via the pass-through CC line. If the UFP is attached using an electronically marked cable, it also applies VCONNpower to the cable CC pin. The TPS25810A-Q1 can identify and report when Type-C audio or debug accessories are attached. The TPS25810A-Q1 device draws less than 0.7 µA (typical) from the AUX pin when no USB load is connected. Additional system power saving is achievable in the S4 and S5 system power states by using theUFPoutput 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 microcontroller in low-power states (S4 and S5). The TPS25810A-Q1 device integrates a 34-mΩ power switch with a fixed 3.4-A current limit independent of the Type-C current advertisement level. TheFAULToutput signals when the switch is in an overcurrent or overtemperature condition. TheCSoutput is used for implementing digital cable compensation for load currents greater than 1.95 A. Cable compensation, also known as line drop compensation, is a means of offsetting voltage droop from the USB power supply to the UFP load.

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 VBUSand communicates the selectable VBUScurrent sourcing capability to the UFP via the passthrough CC line. If the UFP is attached using an electronically marked cable, the TPS25810 also applies VCONNpower 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 theUFPoutput to disable the high power 5-V supply when no UFP is attached.
