The TPS26744E-Q1 is a stand-alone dual-port USB Type-C and power delivery (PD) source controller for any automotive USB-C port application including extended power range (EPR) voltages. The TPS26744E-Q1 is capable of supporting all USB-PD power supply negotiation options for standard power range (SPR) and EPR. The TPS26744E-Q1 automatically identifies USB-C cable capabilities, and adjusts for the maximum current allowed by the cable, without requiring an external 5V supply for VCONN. The TPS26744E-Q1 supports DisplayPort over USB-C and legacy D+/D- charging.
The TPS26744E-Q1 controls a DC/DC via I2C or PWM to achieve a complete USB-C PD application. The TPS26744E-Q1 has SYNC outputs to keep external DC/DC switching out-of-phase for each port, with dual-random spread-spectrum (DRSS).
The TPS26744E-Q1 has integrated protections for thermal and input voltage monitoring for power foldback, VBUS high/low monitoring, and liquid detection along with corrosion mitigation.
The TPS26744E-Q1 also supports USB-C Alternate Modes such as DisplayPort. The TPS26744E-Q1 offers multiple interface options for the system including I2C and LIN support, along with configurable GPIOs.

TPS26742EQ1EVM — TPS26742E-Q1 評估模組
TPS26744EQ1EVM — TPS26744E-Q1 評估模組
PMP23501 — 車用、24V 至 60V 輸入、雙埠 USB 電力傳輸，每埠最大 60W 參考設計
PMP23618 — 具備雙連接埠，每埠最大輸出 180W，支援 24V 至 60V 輸入的車用 USB 電源傳輸參考設計
此參考設計可為汽車先進駕駛輔助系統 (ADAS)、車載資訊娛樂系統及儀錶板應用提供動力。操作範圍為 24V 至 60VDC 輸入，並著重 48VDC 電源。提供兩個 USB PD 輸出，允許為各種高功率裝置充電。此設計在 48Vin 下輸出最大 180W、36V、5A 時的轉換效率達 98.1%。測試報告包含完整輸入範圍內的運作資料，並包含 5Vout 和 36Vout 之間的輸出轉換，以顯示最糟的情境。此測試報告也會展示 180W 輸出和電壓漣波的熱影像。此參考設計為 PMP23501 電路板的延伸功率範圍版本。
PMP31344 — 車用、12V 輸入、140W 雙埠 USB 電力傳輸，支援 DisplayPort™ ALT 模式參考設計
此參考設計為車用 USB 擴充功率範圍 (EPR) 系統，可為兩個 USB Type-C® 埠同時提供電源與數位通訊功能。連接 USB-C 纜線時，TPS26744E-Q1 會與插入式裝置協商目標輸出電壓和最大電流。接著控制器會啟用並適當驅動處理電力傳輸的降壓升壓控制器 (LM251772)。
在通訊端，TPS26744E-Q1 可與連接的 USB 裝置（例如手機或筆記型電腦）協商 USB-DP 模式的選擇。接著，顯示器強制轉型則可透過 USB 多工器 (MUX) (TUSB564-Q1)、DP MUX (TS3DV642) 及平板顯示器 (FPD)-Link 序列器啟用。
