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.
