PRODUCTION DATA. TPS25740, TPS25740A SLVSDG8A – APRIL 2016 – REVISED MAY 2016 TPS25740, TPS25740A USB Type-C and USB PD Source Controller 1 1 Features 1 • USB Power Delivery (PD) 2.0 Certified Provider, USB Type-C™ Rev. 1.2 Compliant Source • Pin-Selectable Voltage Advertisement – 5 V, 12 V, and/or 20 V (TPS25740) – 5 V, 9 V, and/or 15 V (TPS25740A) • Pin-Selectable Peak Power Settings – 12 options 15 W – 100W (TPS25740) – 11 options 15 W – 81W (TPS25740A) • High Voltage and Safety Integration – Overvoltage, Overcurrent, Overtemperature Protection and VBUS Discharge – IEC 61000-4-2 Protection on CC1 and CC2 – Input Pin for Fast Shutdown Under Fault – Control of External N-ch MOSFET – 2-pin External Power Supply Control – Wide VIN Supply (4.65 V – 25 V) • Below 10 µA Quiescent Current when Unattached • Port Attachment Indicator • Built-In 1.8 V at 35 mA Supply Output 2 Applications • USB-PD Adaptor (data-less) • Dedicated Charging Port (data-less) • Power Hub (data-less) • Power Bank • Cigarette Lighter Adaptor (CLA) 3 Description The TPS25740, TPS25740A implements a source that is compliant to USB Power Delivery 2.0 version 1.2 and Type-C revision 1.2. 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 up to three different voltages using USB Power Delivery. Four input pins (PSEL, HIPWR, PCTRL, and (EN12V or EN9V) are used to configure the voltages and currents advertised. The device uses the CTL1 and CTL2 pins to select one of three voltages 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 TPS25740, TPS25740A 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 (UFP) 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).
