Interface ICs
An interface IC is a type of integrated circuit that is designed to facilitate communication between two devices or systems. These devices are commonly used in electronic systems to enable the transfer of data and control signals between different components or subsystems. Some common use cases for interface ICs include connecting microcontrollers to peripherals such as sensors or displays, linking multiple processors together in a network, and enabling communication between devices using different communication protocols. Flux.ai has the world's largest community-driven public library of interface ICs, with footprints, symbols, datasheets, and simulation models. This library is a valuable resource for engineers and designers who need access to accurate and up-to-date information on these important components. Whether you are working on a new design project or simply looking to learn more about interface ICs, Flux.ai is an excellent resource to help you find the information you need.
STUSB4500QTR
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<sub>SYS</sub>: 3.0 V – 5.5 V V<sub>DD</sub>: 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
