Texas Instruments TPS25740BRGER

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).
