The FAN7310 is a high-voltage gate driver IC from Fairchild Semiconductor (now ON Semiconductor), designed for driving N-channel MOSFETs in high-voltage applications, particularly in half-bridge and full-bridge converters. It is commonly used in LCD TVs, PDP TVs, and other display applications.

Applications

• LCD TVs: Used to drive the backlight inverter circuits.
• PDP TVs: Employed in the sustain and address driver circuits.
• Lighting Ballasts: Suitable for driving MOSFETs in electronic ballasts for fluorescent lamps.
• Half-Bridge and Full-Bridge Converters: Used in power supplies and inverters requiring high-voltage isolation.
• Industrial Power Supplies: Applied in various industrial power supply applications.

Features

• High Voltage Capability: Supports high-voltage operation, typically up to 600V.
• Floating Channel Designed for Bootstrap Operation: Allows for high-side gate driving using a bootstrap circuit.
• Matched Propagation Delay for Both Channels: Ensures accurate timing and prevents shoot-through in bridge configurations.
• Integrated Dead-Time Control: Incorporates dead-time control to prevent simultaneous conduction of both MOSFETs.
• Under-Voltage Lockout (UVLO): Provides UVLO protection to prevent MOSFETs from operating at insufficient gate voltage.
• CMOS Logic Compatible Inputs: Enables easy interfacing with standard CMOS logic devices.

Benefits

• Simplified High-Voltage Drive: Eases the design of high-voltage gate drive circuits.
• Improved Efficiency: Minimizes switching losses and enhances overall system efficiency.
• Enhanced Reliability: Protects MOSFETs from damage due to UVLO and shoot-through conditions.
• Reduced Component Count: Integrates essential gate drive functions, reducing the number of external components required.
