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 is capable of supporting all USBPD

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 USBC

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.
