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

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.

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).
