STUSB4500LBJR

Controllers Overview

The STUSB4500LBJR is a standalone USB Type-C sink controller designed for 5 V-only applications up to 3 A (15 W max.). 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 against short-circuits to VBUS up to 22 V. It includes integrated VBUS switch gate drivers, voltage monitoring, and dual power supply options (VSYS and VDD). Certified for USB Type-C rev 1.4 and USB PD rev 2.0, it ensures interoperability with USB PD rev 3.0.

Controllers Feature Summary

• Auto-run Type-C sink controller operation for 5 V devices
• Dead battery mode support for immediate charging from discharged state
• Integrated VBUS switch gate drivers and voltage monitoring
• High voltage capability on VBUS pins and CC pin short-to-VBUS protection

Controllers Applications

• Printers, camcorders, cameras
• IoT, drones, accessories and battery powered devices
• Computer accessories (keyboards, mouse)
• Toys, gaming, POS, scanner, LED lighting
• Healthcare, e-cigarettes, handheld devices

Controllers Procurement Notes

Verify the specific ordering suffix BJR corresponds to the WLCSP-25 package variant as indicated in the product summary table. Confirm that the component status remains Active before finalizing procurement plans. Ensure compatibility with the required I²C interface settings and NVM customization needs for the target application design.

Controllers Selection Notes

Select this component for 5 V sink applications requiring up to 3 A current capability. It is suitable for systems needing dead battery mode support or zero consumption when unattached. Consider the WLCSP-25 package size constraints and the need for external decoupling capacitors on regulator outputs. Verify if MCU integration via I²C is required for dynamic configuration or if auto-run mode suffices.

Controllers Part Context

The STUSB4500LBJR belongs to the STUSB4500L series of standalone USB Type-C port controllers. It complements the higher-power STUSB4500 by focusing on 5 V-only sink devices. This series addresses the need for certified, auto-run Type-C controllers that simplify design for consumer electronics and IoT devices requiring reliable power negotiation.

Controllers Replacement Considerations

STUSB4500QTR serves as a functional equivalent within the same family but utilizes a QFN-24 EP package instead of WLCSP-25. Designers must account for significant footprint and pinout differences when substituting between these package types.
