Features, Applications

USB Type-C Rel. 1.3 Compliant Source Controller STD/1.5-A Current Capability Advertisement on CC Lines Connector Attach/Detach Detection Super Speed Polarity Determination VBUS and VCONN (TPS25820) Application and Discharge with Internal Fixed Current Limit 1.0-A (typ) Operating Current with Nothing Attached to the Type-C Connector 64-m (typ) High-Side OUT MOSFET Meets USB Current-Limiting Requirements 1.7-A OUT Current Limit with 7% Accuracy Fast Overcurrent Response 1.5 s (Typical) CC1 and CC2 8-kV Contact and 15-kV Air Discharge ESD Rating (IEC-61000-4-2)

The is a USB Type-C source controller with an integrated 1.5 A-rated USB power switch. The TPS25820/21 monitors the Type-C configuration channel (CC) lines to determine when a USB sink is attached. If a sink is attached, the TPS25820/21 applies power to VBUS and communicates the selectable VBUS current sourcing capability to the sink via the pass through CC line. If the sink is attached with an electronically marked cable, the TPS25820 also applies VCONN power to the cable VCONN pin. The TPS25821 does not apply VCONN power and is for functions where VCONN is not needed such as USB 2.0 and data-less charging implementations. The TPS25820/21 draws 1.0 A (typ) when nothing is attached. The FAULT output signals when the switch in an overcurrent or overtemperature condition. The SINK output signals when a sink is attached and the POL output signals the polarity of the cable superspeed lines. Device Information(1)

PIN NAME IN CHG EN FAULT SINK POL REF CC1 GND CC2 OUT Thermal Pad NUMBER I/O I/O O DESCRIPTION Device input supply. VBUS internal power switch input supply. VCONN internal power switch input supply for the TPS25820. Charge logic input to select between standard USB or 1.5-A Type-C current sourcing ability. Logic input to turn the device on and off. Open-drain logic output that asserts when the device is in overtemperature and/or VBUS is in current limit condition. Open-drain logic output that asserts when a Type-C Sink is identified on the CC lines. Open-drain logic output that signals which Type-C CC pin is connected to the cable CC line. This gives the information needed to mux the super speed lines. Asserted when the CC2 pin is connected to the cable CC line. Analog input used to make a current reference. Connect 100-ppm, 100-k resistor between this pin and GND. Analog input/output that connects to the Type-C receptacle CC1 pin. Ground Analog input/output that connects to the Type-C receptacle CC2 pin. VBUS power switch output. Thermal pad on bottom of package.
