Single Port USB-C PD Charging

Overview

The UPD11210F Single Port USB-PD Charger is an automotive-grade solution designed to address the increasing power demands of contemporary vehicles. AEC-Q100 qualified, it ensures high reliability and performance in harsh automotive environments. Its integrated design minimises electromagnetic interference (EMI) and enhances charging efficiency through intelligent power management. The solution also supports over-the-air (OTA) updates, integrated authentication for secure communication, and an optional Local Interconnect Network (LIN) interface for enhanced connectivity.

An industry first: the UPD11210F delivers 100 W per port with integrated FETs, significantly reducing solution size and complexity. For next-generation architectures, it supports a 48 V input and delivers up to 240 W per port to meet the demands of zonal architectures and rising customer power requirements. The UPD11210F is designed to provide efficient power delivery to a single device, making it ideal for spatially distributed ports within a vehicle. The system draws power from the main battery and includes reverse battery protection to prevent damage caused by incorrect battery connections.

The core of the system is the USB-PD single port module, which comprises the following 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 serves as the interface for connecting and charging devices

Optional LIN PHY component, which is available upon request
