TPS2121RUXR Description

Short technical summary and product information.

The Texas Instruments TPS2121RUXR is an active power multiplexer designed for efficient power management in various applications. It supports an input voltage range from 2.7V to 22V, with an absolute maximum input voltage of 24V. The device features two input channels (IN1, IN2), each capable of handling a maximum output current of 4A, and a maximum total current (Imax) of 4.5A.

 

Key electrical characteristics include a low typical on-resistance of 56mΩ for both input channels, minimizing power loss. The TPS2121RUXR offers adjustable features such as current limit (1A to 4.5A), overvoltage protection, and soft start time, providing design flexibility. It also includes essential protection features like reverse current blocking, short circuit protection, and thermal shutdown.

 

Packaged in a 12-VQFN-HR (2x2.5 mm) surface-mount package, this power mux is suitable for space-constrained designs. The operating temperature range is -40°C to 125°C (TJ). Additional features include a power good signal and channel status indication, enhancing system monitoring and control.
