TPS2546RTET Description

Short technical summary and product information.

The Texas Instruments TPS2546RTET is an active USB charging port controller and power switch designed for efficient power management. It supports CDP/SDP auto switching and offers an adjustable current limit ranging from 0.2A to 2.5A, with a maximum continuous current of 2.7A.

 

This device operates within an input voltage range of 4.5V to 5.5V and features an integrated 73-mΩ high-side MOSFET. It includes fault protection for current limiting, over-temperature conditions, and undervoltage lockout (UVLO). The TPS2546RTET is available in a 16-WQFN (3mm x 3mm) package, suitable for surface mount applications.

 

Key functionalities include load detection for power supply control in S4/S5 states and port power management in all charge modes. It is compatible with USB 2.0 and 3.0 power switch requirements and offers an 8-kV ESD rating on DM/DP pins. The device also supports various non-BC1.2 charging modes and sleep-mode charging.
