High-side switches

Deliver precision, protection and performance for a range of loads

Browse by category

Achieve reliable power control with our portfolio of high-side switches for 12V, 24V and 48V systems. Whether in an automotive vehicle or industrial programmable logic controller (PLC), these smart power switches help protect and diagnose short-to-ground, open-load, overtemperature or other serious fault conditions. A selection of drain-to source on-resistance options, along with adjustable current limiting and high-accuracy current sensing, optimize switching for resistive, inductive and capacitive loads. Our wide voltage support empowers scalable, high-performance designs across automotive and industrial systems, from zone and body controllers and power distribution units to safety PLCs and 48V robotics.
