FAN7391MX High-Side / Low-Side Gate Driver IC for High-Voltage Power Systems
The FAN7391MX is a high-current, high-side and low-side gate driver IC designed to control MOSFETs and IGBTs in high-voltage power systems. With a floating channel supporting up to +600V, it enables reliable switching performance in demanding industrial environments.
Thanks to its common-mode noise cancellation and high dv/dt immunity, the FAN7391MX is suitable for applications requiring stable switching under harsh electrical noise conditions, such as SMPS units, motor drives, HID lamp ballasts, and PSU control circuits.
Key Features and Benefits
- High-side and low-side MOSFET/IGBT driving capability
- Floating channel supports up to +600V
- High current drive capability with minimized cross-conduction
- Buffered output stage using all-NMOS for strong gate drive
- dv/dt noise immunity with common-mode cancellation
- Suitable for high-speed switching power electronics
