描述Without any firmware configuration, the TPS25740B implements a source that is certifiedfor 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 CCpin to detect when a USB Type-C sink is attached, then it enables a N-ch MOSFET gate driver to turnon 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 deviceuses the CTL1, CTL2, and CTL3 pins to select the voltage from the power supply based on the voltagerequested by the attached sink. The device automatically handles discharging the VBUS output perUSB PD requirements. The TPS25740B typically draws 8.5 µA (or 5.8 µA if VDD = 3.3 V) when no device isattached. 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).特性 USB PD 2.0 Certified (TID# 1030004) and USB PD 3.0 Compliant Provider, Pin-Selectable Voltage Advertisement 5 V, 9 V, 12 V, and 15 V 5 V, 9 V, 15 V, and 20 V Pin-Selectable Peak Power Settings 8 Options 18 W – 100WHigh Voltage and Safety IntegrationOvervoltage, Overcurrent, Overtemperature Protection andVBUS Discharge IEC 61000-4-2 Protection on CC1 and CC2Input Pin for Fast Shutdown Under FaultControl ofExternal N-ch MOSFET3-Pin External Power SupplyControlWide VIN Supply (4.65 V – 25 V) Below 10 µA Quiescent Current WhenUnattachedPort Attachment Indicator Self-Directed Port Power Management for Dual-PortApplicationsAll trademarks are the property of their respective owners.
