www.DataSheet4U.com FAN7384 Half-Bridge Gate-Drive IC November 2006 FAN7384 Half-Bridge Gate-Drive IC Features „ Floating Channel for Bootstrap Operation to +600V „ Typically 250mA/500mA Sourcing/Sinking Current „ „ „ „ „ „ „ „ „ „ „ Description The FAN7384 is a monolithic half-bridge gate-drive IC designed for high voltage, high speed driving MOSFETs and IGBTs operating up to +600V. 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 = -9.8V (typical) for VBS =15V. The UVLO circuits prevent malfunction when VDD and VBS are lower than the specified threshold voltage. Output drivers typically source/sink 250mA/500mA, respectively, which is suitable for half-bridge and fullbridge applications in motor drive systems. Driving Capability for Both Channels Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VDD=VBS=15V Matched Propagation Delay Below 50ns Output In-Phase with Input Signal 3.3V and 5V Input Logic Compatible Built-in Shoot-Through Prevention Logic Built-in Common Mode dv/dt Noise Canceling Circuit Built-in UVLO Functions for Both Channels Built-in Cycle-by-Cycle Shutdown Function Built-in Soft-Off Function Built-in Bi-Directional Fault Function Built-in Short-Circuit Protection Function 14-SOP Applications „ Motor Inverter Driver „ Normal Half-Bridge and Fu...
