USB Type-C™ Rev 1.2 and USB PD Source Controllers


Not Recommended for New Designs (NRND)

Replaced By TPS65987D – The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.


The TPS25741, TPS25741A implements a source compliant to USB Power Delivery 2.0 and USB Type-C revision 1.2. It can be used in either a power mux or DC-DC implementation shown in the figure below.

The device monitors the CC pin to detect a USB Type-C sink attachment, then enables the GDNG and G5V gate drivers to apply 5 V to VBUS (refer to figure below). It then offers up to three voltages using USB Power Delivery. In order to source the second voltage the G5V gate driver is disabled and the GDPG gate driver is enabled. In power mux implementations all gate drivers are used and the CTL pins are not necessary. In DC-DC implementations only the GDNG gate driver is necessary and the CTL pins program the power supply for the required voltage. The device automatically discharges VBUS per USB Power Delivery requirements. The PSEL, HIPWR, PCTRL, and EN9V/EN12V pins are used to configure the voltages and currents advertised.

The device typically draws 5.4 µA (8 µA if VDD = 0 V) when no device is attached. The Port Attachment indicator (UFP or DVDD) outputs may be used to disable the power source until a sink is attached for more system power savings.

Protection features include over-voltage, over-current, over-temperature, IEC for CC pins, and system override of gate drivers (GD).
