STUSB4500LQTR

Controllers Overview

The STUSB4500LQTR is a standalone USB Type-C sink controller designed for 5 V-only applications up to 3 A (15 W). It operates in auto-run mode without MCU support, utilizing integrated non-volatile memory for PDO configuration. The device supports dead battery mode and features high voltage protection on CC pins up to 22 V and VBUS pins up to 28 V. It includes integrated VBUS switch gate drivers, voltage monitoring, and dual power supply options (VSYS: 3.0–5.5 V; VDD: 3.3–6 V). Operating temperature ranges from -40 °C to +105 °C with I²C interface speeds up to 400 kb/s.

Controllers Feature Summary

• Auto-run Type-C sink controller supporting dead battery mode
• Integrated VBUS switch gate drivers and voltage monitoring
• High voltage protection on CC pins up to 22 V and VBUS pins up to 28 V
• Source power budget reporting for default, 1.5 A, and 3 A currents

Controllers Applications

• Printers, camcorders, and cameras
• IoT devices, drones, and battery-powered accessories
• Computer peripherals such as keyboards and mice
• Toys, gaming equipment, POS systems, and LED lighting
• Healthcare devices, e-cigarettes, and handheld electronics

Controllers Procurement Notes

Verify the specific ordering suffix QTR against the manufacturer's current datasheet revision to confirm package type and reel specifications. Ensure compatibility with system voltage requirements and I²C address configurations before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Controllers Selection Notes

Select this component for 5 V sink applications requiring standalone operation without external microcontrollers. It is suitable for replacing USB STD-B and micro-B connectors in Type-C designs. Consider NVM customization for specific start-up profiles and GPIO configurations. Verify that the application supports the required dead battery mode connections if applicable.

Controllers Part Context

The STUSB4500L belongs to the STUSB4500 series of USB Power Delivery controllers. While the standard STUSB4500 supports up to 100 W (20 V), the STUSB4500L variant is optimized for 5 V-only sink devices. Both share similar auto-run capabilities and certification status but differ in maximum voltage handling and power delivery profiles.

Controllers Replacement Considerations

STUSB4500BJR is a pin-compatible alternative in WLCSP-25 packaging. Standard STUSB4500 offers higher power capabilities but requires different voltage handling considerations.
