Key Features of the STUSB4531 Controller
The STUSB4531 controller integrates a hardware-embedded USB PD stack with proprietary algorithms, enabling power delivery negotiation without requiring external software. This functionality is particularly beneficial for automatic high-power profile charging, especially when batteries are fully discharged.
It also features a hybrid mode, which allows an external application processor to interact with the USB PD stack. This mode facilitates the flexible implementation of optional USB PD features such as alternate modes, battery communication, data role swap, and vendor-defined messages (VDM) with minimal external software.
The STUSB4531 controller supports the adoption of USB-C in charging and powered devices, aligning with international regulatory efforts to reduce electronic waste. It is certified to the latest USB Type-C® 2.4 and USB PD 3.2 standards and complies with IEC 62680 for EU conformity.
Applications and Development Support
The STUSB4531 is an optimal solution for replacing USB micro-B and DC barrel connectors. Its applications span across set-top boxes, cameras, medical devices, handheld devices, LED lighting, battery charging equipment, and VBUS powered devices.
For development purposes, engineers can utilize STMicroelectronics’ EVAL-SCS007V1 evaluation board and EVAL-SCS006V1 reference design with the STUSB4531 controller.
