3 Description
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 V_BUS (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 V_BUS 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).
