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.
The TPS25740, TPS25740A typically draws 8.5 µA
(or 5.8 µA if VDD = 3.3 V) when no device is
attached.
Additional
system
power
saving
is
achievable by using the Port Attachment Indicator
(UFP) output to disable the power source when no
device is attached.
Protection features include overvoltage protection,
overcurrent protection, over-temperature protection,
IEC for CC pins, and system override to disable the
gate driver (GD).
