3 Description
Without any firmware configuration, the TPS25740B
implements a source that is certified for USB Power
Delivery 2.0 version 1.2 and Type-C revision 1.2
designed to minimize time to market. The device is
designed to work seamlessly with any USB PD 3.0
compliant sink. 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 four different voltages using USB Power
Delivery. Three input pins (PSEL, HIPWR, and
PCTRL) are used to configure the voltages and
currents advertised. The device uses the CTL1,
CTL2, and CTL3 pins to select the voltage 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 TPS25740B 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 (DVDD) 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).
