Power trends
Power switches for power density
With the integration of active and passive components, power switches enable you to achieve higher power density for your power distribution. Our power switches reduce power dissipation and add a number of protection and diagnostic features to ensure your system is fully protected without compromising board space. Our devices also reduce your footprint or improve heat dissipation.
Power switches for low quiescent current (IQ)
Extend battery run-time without giving up system performance with our power switches. Our power switches can reduce leakage current when modules are powered off with their ultra-low shutdown current (ISD). Our devices also offer solutions with low IQ, which can help to extend battery life when the system is operating in a standby mode.

Isolation
Improve system safety with higher reliability isolation compared to electromechanical and traditional photorelay solutions. Using industry-leading capacitive and magnetic isolation technology, our solid-state relay (SSR) portfolio of isolated switches and drivers forms a complete isolated solid-state relay solution with no moving parts. Our SSRs completely integrate the power and signal transfer over an isolation barrier in a single chip reducing solution size and cost for automotive and industrial applications.
