The TPS2543RTET from Texas Instruments is a versatile USB charging port controller and power switch designed for applications requiring robust power delivery and load detection. It features an integrated USB 2.0 high-speed data line switch, supporting various charging schemes including USB Battery Charging Specification 1.2 and Chinese Telecom Standard YD/T 1591-2009.
This device operates within a 4.5V to 5.5V input voltage range and offers a continuous output current of up to 2.5A, with an adjustable current limit up to 3A. The typical on-resistance is 73mOhm, ensuring efficient power transfer. It includes fault protection features such as current limiting, over-temperature protection, and undervoltage lockout (UVLO).
The TPS2543RTET is available in a 16-WQFN (3x3) package, suitable for surface mount applications. Its design supports automatic selection of D+/D- modes for attached devices and provides load detection via the STATUS pin, enabling power supply control in S4/S5 charging states and port power management in multi-port applications. It is also compatible with USB 2.0 and 3.0 power switch requirements.
