Gate Driver FAQ

Does the FAN7190MX-F085 support isolated communication?

No, the FAN7190MX-F085 is a non-isolated gate driver. It requires a common ground reference between the control logic and the power stage.

What is the maximum voltage rating for the high-side driver?

The datasheet specifies a maximum supply voltage (VCC) of 22 V. The high-side floating supply is typically derived via a bootstrap capacitor connected to this rail.
