STMicroelectronics STUSB47 Autonomous USB PD Controllers
STMicroelectronics STUSB47 Autonomous USB PD Controllers are USB power delivery controllers communicating over Type-C™ configuration channel pins (CC). The controllers negotiate a given amount of power to be sourced to an inquiring consumer device. The STUSB47 addresses provider/DFP devices like notebooks, tablets, and AC adapters. The devices can handle any connections to a UFP or DRP without any MCU attachment support, from device attachment to power negotiation, including VBUS discharge and protections.
Features
- USB power delivery (PD) controller
- Type-C attach and cable orientation detection
- Single role: provider - DFP
- Full hardware solution - no software
- I2C interface (optional connection to MCU)
- Support all USB PD profiles: up to 5 power data objects (PDO)
- Configurable startup profiles
- Integrated VBUS voltage monitoring
- Internal and/or external VBUS discharge path
- Short-to-VBUS protections on CC pins (22V) and VBUS pins (28V)
- Temperature range: -40°C up to 105°C
- Dual power supply (VSYS and/or VDD):
- VSYS = [3.0V; 5.5V]
- VDD = [4.1V; 22V]
- Fully compatible with:
- USB Type-C™ rev 1.2
- USB PD rev 2.0
Applications
- AC adapters and power supplies for: computer, consumer or portable consumer applications
- Smart plugs and wall adapters
- Power hubs and docking stations
- Displays
- Any Type-C source device
