Controllers datasheet and documents for STUSB4500QTR

STUSB4500QTR

Controllers Overview

The STUSB4500QTR is a standalone USB Power Delivery sink controller in a QFN-24 EP (4x4 mm) package. It supports up to 100 W power sinking (20 V; 5 A) and negotiates contracts without MCU support via auto-run mode. PDO profiles are stored in integrated non-volatile memory. Key electrical parameters include a VDD range of 4.1 V to 22 V, a VSYS range of 3.0 V to 5.5 V, and an operating temperature from -40 °C to 105 °C. The device features short-to-VBUS protection on CC pins up to 22 V and high voltage capability on VBUS pins up to 28 V.

Controllers Feature Summary

Autonomous power negotiation through proprietary algorithms without MCU intervention
Dead battery mode enabling system startup directly from external VBUS supply
Integrated high voltage protections for CC and VBUS pins against shorts and overvoltage

Controllers Applications

Printers, camcorders, and cameras
IoT devices, drones, and accessories
LED lighting and industrial equipment
Healthcare and handheld devices

Controllers Procurement Notes

Verify the specific ordering suffix QTR corresponds to the QFN-24 EP package variant. Confirm that the NVM configuration matches the required PDO profiles for the target application. Ensure ESD handling procedures meet the specified 3 kV HBM and 1.5 kV CDM ratings during assembly.

Controllers Selection Notes

Select this component for applications requiring autonomous USB PD sink functionality without a host microcontroller. It is suitable for systems needing dead battery mode support or dual high-power charging paths. Verify compatibility with USB Type-C rev 1.2 and USB PD rev 2.0 standards.

Controllers Part Context

The STUSB4500 series includes the STUSB4500BJR in a WLCSP-25 package. Both variants serve as standalone USB PD sink controllers with auto-run capabilities. The QTR suffix specifically denotes the surface-mount QFN-24 EP package version.
