Fairchild Fan7390 Data Handbook
Summary
This advanced, high-current gate-drive IC is a sophisticated monolithic device designed for robust power conversion applications. Capable of driving high-speed MOSFETs and IGBTs up to +600V, it ensures stable, reliable operation even under severe common-mode noise conditions. The manual serves as a comprehensive technical reference, detailing features such as built-in Under-Voltage Lockout (UVLO), source/sink capability (4.5A), electrical ratings, pinouts, and application circuits for half-bridge topologies. It is primarily intended for engineers designing motor drives, switching power supplies (SMPS), DC-DC converters, and industrial high-power pulse generation systems.
