PDF datasheet for the Texas Instruments TPS25810, a USB Type-C downstream-facing port controller with an integrated power switch. At 1.49 MB, it documents the pinout, electrical limits, application circuits and typical waveforms. A technician uses it to check supply and enable pins, CC line behaviour and VBUS switching when a USB-C port gives no power. Any PDF reader opens it. Confirm the package and the marking on the chip before using its pin assignments.
