Power muxes are a category of power management devices rather than a specific brand. These devices are commonly used in industrial and electrical applications to switch or multiplex power sources, ensuring uninterrupted power supply and system reliability. Companies like Texas Instruments (USA), ON Semiconductor (USA), and Analog Devices (USA) produce power mux ICs (integrated circuits) for industries such as automotive, telecommunications, and industrial automation. These products enable seamless power source transitions, load sharing, and backup power solutions, catering to critical infrastructure and high-availability systems.
