High-side switch controllers are not a specific brand but a category of electronic components used in industrial and automotive applications. These devices are designed to control high-side switches, which manage power distribution by connecting or disconnecting loads from the power supply. They are commonly produced by semiconductor companies like Infineon Technologies (Germany), Texas Instruments (USA), and STMicroelectronics (Switzerland). High-side switch controllers serve industries such as automotive, industrial automation, and consumer electronics, offering features like overcurrent protection, thermal shutdown, and diagnostics. Key products include intelligent power switches (IPS) and MOSFET drivers, enabling efficient power management in systems like motor control, lighting, and battery management.
