Overview

The STUSB4500QTR is a standalone USB Power Delivery (PD) sink controller designed for 'dead battery' applications and migrating devices from barrel jacks to USB-C power. It operates without an external microcontroller for power negotiation, automatically managing up to three configurable Power Data Object (PDO) profiles via internal non-volatile memory.

Why Choose This Part

This controller stands out by offering a standalone 'Auto-run' mode that handles the entire USB PD negotiation process without host software. It features high-voltage robustness with 22V protection on CC pins and 28V capability on VBUS pins, alongside integrated gate drivers for PMOS VBUS switches to reduce external component count.

Applications

Barrel Jack Replacement
Replacing proprietary DC connectors with USB Type-C in consumer electronics and industrial equipment up to 100W.
Dead Battery Equipment
Devices that require high-power PD negotiation immediately upon connection even when the internal battery is fully depleted.
Portable Power Tools
Charging and powering handheld tools using standard USB-C PD power bricks.
Industrial Handhelds
Ruggedized mobile devices requiring robust CC pin protection and high-voltage VBUS monitoring.

Getting Started

To evaluate the chip, engineers typically use the EVAL-SCS001V1 expansion board or the P-NUCLEO-USB002 development kit. Configuration is performed using the STUSB4500 GUI through an I2C interface to define voltage and current profiles in the device's NVM.
