Isolation

Isolated gate driver

Highly robust, flexible, and universally compatible devices for many applications

TI's flexible and universally compatible isolated gate drivers enable you to build smaller, more robust designs for many applications.  

Basic isolation

Basic isolation provides a single level of electrical isolation up to 3kVrms and sufficient protection against electrical shock. Solutions provide robust ground bounce protection while meeting high voltage guidelines.

Reinforced isolation

Reinforced isolation enables up to a 5.7kVrms isolation rating to safely protect humans and equipment from electric shock. Reinforced solutions offer higher working voltages, wider creepage and clearance for improved system robustness.
