Welcome to Getting to Know Your Gate Driver. This is a multi-part video series where we will introduce important gate driver parameters, tell you why they are important and how they can influence the systems around them. Today I'm going to introduce another important gate driver parameter, VDD.

VDD is the positive supply voltage connected to the drain of the MOSFET or to the collector of the IGBT. For gate drivers, VDD defines the range of drive outputs. So why is it important to your design? There are three benefits of having a wide VDD range.

First, it provides flexibility in system design, which means the same driver can be used in systems with different operating voltages. And it can also drive different types of power switches, like both silicon and silicon carbide fits. Second, it offers robustness in noisy environments or when low-quality power supplies are used. It can effectively prevent your system from being damaged by overshoots or undershoots. Last, but not least, drivers with a wide VDD range can be used in split-rail systems, such as driving IGBTs with both positive and negative supplies.

Overall, a wide VDD provides possibilities of more applications and robustness in extreme conditions. Thanks for watching. To learn more about the gate drivers with wide VDD range, visit ti.com/gatedrivers.
