Power switches
Power on with solutions for your distribution, protection, or diagnostics needs
Power Switches provide an electrical connection from a voltage source or ground to a load. Our diverse portfolio includes several topologies, from simple load switches to smart power switches. Sequencing, protection against common IC events, diagnostic telemetry, and more is made possible with our power switches.
Load switches
Load switches are a simple, cost-effective way to turn on and off your power rails. Reduce your BOM count with an integrated load switch and get to market faster.
eFuses & hot swap controllers
These power path protection devices are used to control load current with integrated or external FETs. Get protected with our extensive feature options.
Smart power switches
Drive and protect an inductive, resistive and capacitive load, while providing real-time diagnostics to your automotive and industrial systems.
Ideal diode & OR-ing controllers
Find the right solution to reduce power loss and thermal dissipation, while protecting your system from reverse polarity and reverse current conditions.
Power muxes
Power multiplexers allow you to switch between subsystems with two different voltage levels. Preserve operating conditions with seamless switchover options.
Low side switches
Unlike other power switch topologies, our low side switches utilize an integrated flyback diode to connect the load to ground.
The six types of power switches
Power switches are used in multiple locations in a design. They provide protection at the input, power distribution throughout the system, and protection at the output for off-board loads. The common use cases for various power switches can be seen below.
