Product Overview
TPS25820 is a Texas Instruments USB Type-C source controller for 5 V source-side Type-C interfaces. The device is listed as USB Type-C Release 1.3 compliant and integrates a 1.5 A USB power switch, with Type-C current advertisement selected by the CHG input and driven on the CC lines as STD / 1.5 A.
The IN pin recommended operating range is 4.5 V to 5.5 V, while EN/CHG inputs support 0 V to 5.5 V with 2 V minimum high-level input and 0.8 V maximum low-level input. The OUT path supports 1.5 A maximum positive source current, a 64 mOhm typical high-side MOSFET, and a 1.6 A to 1.84 A short-circuit current-limit range.
TPS25820 includes VCONN support on CC1 or CC2 with 250 mA maximum recommended VCONN source current. It also specifies VCONN switch resistance, VCONN current limiting, CC discharge behavior, SINK/POL and FAULT open-drain output limits, UVLO, thermal shutdown, and low supply-current operating states. The package is a 12-pin WSON (DSS), 3.00 mm x 2.00 mm nominal body.
