The TPS25741RSMT is an USB Type-C and USB power delivery host port controller in 32 pin VQFN package. It 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 to DC implementation. Device monitors the CC pin to detect a USB Type-C sink attachment, then enables the GDNG and G5V gate drivers to apply 5V to VBUS. It then offers up to three voltages using USB power delivery. In order to source 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 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. It is used in USB data capable, hub downstream ports and automotive infotainment.
