SLVSDG8B – APRIL 2016 – REVISED JUNE 2017 TPS25740, TPS25740A USB Type-C and USB PD Source Controller
1 Features 3 Description The TPS25740, TPS25740A implements a source
that is compliant to USB Power Delivery 2.0 version
1.2 and Type-C revision 1.2. It monitors the CC pin to
detect when a USB Type-C sink is attached, then it
enables a N-ch MOSFET gate driver to turn on
VBUS. The device then offers up to three different
voltages using USB Power Delivery. Four input pins
(PSEL, HIPWR, PCTRL, and (EN12V or EN9V) are
used to configure the voltages and currents
advertised. The device uses the CTL1 and CTL2 pins
to select one of three voltages from the power supply
based on the voltage requested by the attached sink.
The device automatically handles discharging the
VBUS output per USB PD requirements. 1 USB Power Delivery (PD) 2.0 Certified Provider,
