Automotive dual-port USB Type-C PD controller with 240W EPR and DisplayPort alternate mode

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.
