STUSB4500QTR USB Power Delivery Controller
The STUSB4500QTR from STMicroelectronics is a highly integrated USB Power Delivery (PD) controller designed for sink devices. This advanced controller is optimized for simplicity and flexibility, making it an ideal choice for a wide range of applications that require USB Type-C connectivity and PD capability.
Key Features
- USB Type-C Rev 1.2 and USB PD Rev 2.0 compliant
- Integrated VBUS voltage monitoring
- Supports dead battery mode
- Customizable power profiles through non-volatile memory
- Integrated discharge path for VBUS
The STUSB4500QTR enables the negotiation of a power delivery contract with a USB PD source without the need for any microcontroller or software support. It is capable of handling up to 5 power data objects (PDOs), which can be configured via I2C and stored in the device's non-volatile memory, allowing for a flexible and dynamic power supply solution.
With its integrated VBUS voltage monitoring, the device ensures safe operation under varying power conditions. Furthermore, the STUSB4500QTR supports dead battery mode, which allows for a device to be powered from the USB-C port even when the device's battery is completely discharged.
The device comes in a small QFN-24 package, making it suitable for compact designs. Its robust design includes over-voltage, over-current, and over-temperature protection, ensuring reliable operation in a variety of environments.
Whether you're designing a smartphone, a portable battery pack, or any other USB-C powered device, the STUSB4500QTR offers a comprehensive solution for USB Power Delivery with minimal design complexity.
