USB Controller USB 2.0 I2C Interface 24-QFN (4x4) The STUSB4500QTR is a standalone USB Type-C Power Delivery (PD) controller from STMicroelectronics designed for power sink applications (devices that receive power, like chargers, IoT devices, or battery-powered systems). It enables automatic negotiation of USB Power Delivery contracts (up to 100 W: 20 V / 5 A) without requiring an external microcontroller, thanks to its built-in auto-run algorithm. Power profiles (PDOs) can be pre-configured and stored in internal non-volatile memory, simplifying system design and reducing component count. The device is optimized for modern USB-C designs, offering robust protection, high-voltage tolerance, and support for operation even from a dead battery state. Key Features Power Delivery & Control Standalone USB Type-C™ and USB PD sink controller Supports up to 100 W (20 V, 5 A) power negotiation Auto-run mode (no MCU required) for PD negotiation Up to 3 configurable sink PDO profiles stored in NVM Power Management Dead battery mode support (can start with no battery power) Dual power supply inputs: V_SYS: 3.0 V – 5.5 V V_DD: 4.1 V – 22 V Integrated VBUS monitoring and control Integrated Functions Built-in VBUS switch gate drivers (PMOS) Internal/external VBUS discharge paths I²C interface for configuration and monitoring Protection & Reliability Short-to-VBUS protection on CC pins (up to 22 V) High-voltage tolerance: Up to 28 V on VBUS pins ESD protection: 3 kV HBM / 1.5 kV CDM Physical & Environmental Package: QFN-24 (4×4 mm) Operating temperature: –40°C to +105°C Industrial-grade reliability Compliance & Compatibility Certified for: USB Type-C Rev 1.2 USB PD Rev 2.0 Interoperable with USB PD 3.0 #commonpartslibrary #integratedcircuit #usbcontroller
