●Description
●The FAN7389 is a monolithic three-phase half-bridge gate-drive IC designed for high-voltage, high-speed
●driving MOSFETs and IGBTs operating up to +600 V.
●Fairchild’s high-voltage process and common-mode noise canceling technique provide stable operation of
●high-side drivers under high-dv/dt noise circumstances.
●An advanced level-shift circuit allows high-side gate driver operation up to VS = -9.8 V (typical) for VBS =15 V.
●The protection functions include under-voltage lockout and inverter over-current trip with an automatic fault
●clear function.
●Features
● Floating Channel for Bootstrap Operation to +600 V
● Typically 350 mA/650 mA Sourcing/Sinking Current Driving Capability for All Channels
● Extended Allowable Negative VS Swing to -9.8 V for Signal Propagation at VDD=VBS=15 V
● Output In-Phase with Input Signal
