The FAN7393MX is a high-side gate driver IC manufactured by Fairchild/ON Semiconductor. Gate drivers are essential components in power electronics systems, responsible for efficiently switching power MOSFETs or IGBTs (Insulated Gate Bipolar Transistors). A high-side gate driver specifically controls MOSFETs or IGBTs connected to the high-voltage side of a circuit.

Applications:

• Half-bridge and full-bridge converters: Driving the high-side MOSFETs/IGBTs in half-bridge and full-bridge power converters.
• Motor drives: Controlling the switching elements in motor drive inverters.
• Uninterruptible power supplies (UPS): Driving the switching devices in UPS systems.
• Lighting ballast: Controlling the switching devices in electronic lighting ballasts.
• Induction heating: Driving the power devices in induction heating systems.

Features:

• High-side gate drive: Specifically designed to drive high-side MOSFETs/IGBTs.
• Floating channel: Allows for operation with high-voltage rails.
• Bootstrap diode: Integrated bootstrap diode simplifies circuit design.
• Under-voltage lockout (UVLO): Protects the MOSFET/IGBT from operating at low gate voltage.
• Short circuit protection: Provides protection against short circuit conditions.
• RoHS compliant: Meets environmental standards for hazardous substance restriction.

Benefits:

• Efficient switching: Provides efficient and reliable switching of MOSFETs/IGBTs.
• Simplified circuit design: Integrated features reduce the need for external components.
• Improved system reliability: Protection features enhance system reliability.
• Compact design: Enables smaller and lighter power electronics systems.
