3 Description

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 supports all USB-PD power

negotiation options (fixed supply, programmable

power supply (PPS), and adjustable power supply

(AVS)) 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 solution. 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 GPIOs that

can be configured for various functions.
