Single Port USB

Overview

LTSCT’s automotive USB-PD charging solution is engineered to meet the growing power demands of modern vehicles. It is AEC-Q100 qualified, ensuring high reliability and performance in harsh automotive environments. The integrated design reduces electromagnetic interference (EMI) and improves charging efficiency through intelligent power management. Additional features include over the air (OTA) updates, integrated authentication for secure communication, and optional Local Interconnect Network (LIN) support for enhanced connectivity. An industry first, LTSCT’s USB-PD solution delivers 100 W per port with integrated FETs, significantly reducing solution size and complexity. The next-generation variant supports a 48 V input and delivers up to 240 W per port, aligning with the needs of zonal architectures and increasing power demands.

Single port USB-PD charging solutions are designed to efficiently power individual devices, making them ideal for spatially distributed ports within a vehicle. Power is sourced from the main battery and protected by reverse battery protection to prevent damage from incorrect connections. At the core of the system is the USB-PD single port module, which includes several key components:

PD controller for managing power delivery

DC/DC converter for voltage regulation

ESD protection to safeguard against electrostatic discharge

USB Type-C port serving as the interface for connecting and charging devices

Optional LIN PHY component, available upon request
