# STUSB4500QTR (Component)

## Description

USB Controller USB 2\.0 I2C Interface 24\-QFN \(4x4\) 
The STUSB4500QTR is a standalone USB Type\-C Power Delivery \(PD\) controller from STMicroelectronics designed for power sink applications \(devices that receive power, like chargers, IoT devices, or battery\-powered systems\)\.

It enables automatic negotiation of USB Power Delivery contracts \(up to 100 W: 20 V / 5 A\) without requiring an external microcontroller, thanks to its built\-in auto\-run algorithm\. Power profiles \(PDOs\) can be pre\-configured and stored in internal non\-volatile memory, simplifying system design and reducing component count\.

The device is optimized for modern USB\-C designs, offering robust protection, high\-voltage tolerance, and support for operation even from a dead battery state\.
