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.
