High-side switches are not a specific brand but a category of electronic components used in power management applications. These switches are typically produced by semiconductor companies such as Infineon Technologies (Germany), STMicroelectronics (Switzerland/France), and Texas Instruments (USA). They are widely used in automotive, industrial, and consumer electronics for controlling high-voltage loads with low-voltage signals. Key products include intelligent power switches, MOSFET drivers, and integrated circuits designed for robust performance in harsh environments.
