TPS2546 Description

Short technical summary and product information.

The Texas Instruments TPS2546 is an integrated circuit designed for USB charging applications. It functions as both a charging port controller and a power switch, supporting multiple USB Battery Charging Specification 1.2 modes, including CDP/DCP, and shorted mode per YD/T 1591-2009.

 

Key electrical characteristics include an operating voltage range of 4.5 V to 5.5 V. The device features an integrated 73-mΩ (typical) high-side MOSFET and an adjustable current limit that can be set up to 2.5 A. It also provides load detection capabilities for power supply control and port power management.

 

The TPS2546 is available in a 16-pin WQFN package measuring 3.00 mm x 3.00 mm. It is designed for surface mount applications and offers an 8-kV ESD rating on its DM/DP pins, making it suitable for USB ports in host and hub applications, as well as in notebook and desktop PCs.
