PMP31344
Automotive, 12V input, 140W two-port USB Power Delivery with DisplayPort™ ALT mode reference design
PMP31344
概覽
This reference design represents an automotive USB Extended Power Range (EPR) system, providing both power and digital communication to two USB Type-C® ports. When connecting a USB-C cable, the TPS26744E-Q1 negotiates a target output voltage and maximum current with the plugged-in device. The controller then enables and properly drives a buck boost controller (LM251772), that handles the power transfer.
From the communication side, the TPS26744E-Q1 can negotiate with the connected USB device, for example, cellphones or laptops for USB-DP mode selection. Then the display casting is enabled through USB multiplexer (MUX) (TUSB564-Q1), DP MUX (TS3DV642), and Flat Panel Display (FPD)-Link serializer.
特點
- 12V battery system
- Dual ports USB PD charging, 140W per port
- Supports USB DP ALT mode
- DP to FPD-Link bridge to support remote display casting
