Conclusion

In industrial and automotive applications, isolation enables communication between different voltage domains by protecting low-voltage circuitry from high-voltage faults and maintaining signal integrity by breaking ground loops. Of the different dielectric materials available for isolation, the SiO2 dielectric used in TI’s capacitive isolators offers some of the highest lifetimes in the industry, along with stability over moisture and temperature. TI’s integrated transformer technology enables high-density isolated DC/DC power conversion while lowering EMI.

The TI portfolio of signal and power isolators helps engineers ensure compliance with the most stringent isolation system requirements.
