TPS2543QRTETQ1 Description

Short technical summary and product information.

The TPS2543-Q1 from Texas Instruments is an automotive-qualified USB charging port controller and power switch. It integrates a USB 2.0 high-speed data line switch, providing electrical signatures to support various charging schemes, including BC1.2 compliant and non-BC1.2 compliant devices.

 

Key electrical characteristics include a low 73mΩ (typ) high-side MOSFET, adjustable current limiting up to 3A, and an operating voltage range of 4.5V to 5.5V. The device operates within a temperature range of -40°C to 125°C.

 

This power switch supports advanced power management features such as power wake for S4/S5 charging control and port power management (PPM) for multi-port applications. It also enables system wake-up from S3 using a low-speed mouse or keyboard. Load detection is integrated for power supply control.

 

The TPS2543-Q1 is available in a 16-WQFN (3x3) package and is suitable for surface mount applications. It is AEC-Q100 qualified, making it a robust choice for automotive USB charging ports.
