FAN7382 Half-Bridge Gate-Driver IC January 2007 FAN7382 Half-Bridge Gate-Driver IC Features Floating Channels Designed for Bootstrap Operation to +600V Typically 350mA/650mA Sourcing/Sinking Current Driving Capability for Both Channels Common-Mode dv/dt Noise Canceling Circuit Extended Allowable Negative VS Swing to -9V for Signal Propagation at VCC=VBS=15V VCC & VBS Supply Range from 10V to 20V UVLO Functions for Both Channels TTL Compatible Input Logic Threshold Levels Matched Propagation Delay Below 50nsec Output In-phase with Input Description The FAN7382, a monolithic half-bridge gate-driver IC, can drive MOSFETs and IGBTs that operate up to +600V. Fairchild’s high-voltage process and commonmode noise canceling technique provides stable operation of the high-side driver 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 input logic level is compatible with standard TTL-series logic gates. UVLO circuits for both channels prevent malfunction when VCC or VBS is lower than the specified threshold voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for fluorescent lamp ballasts, PDP scan drivers, motor controls, etc. Applications PDP Scan Driver Fluorescent Lamp Ballast SMPS Motor Driver 8-SOP 8-DIP 14-SOP Ordering Information Part Number FAN7382N FAN7382M (1) Package 8-DIP 8-SOP 14-SOP Pb-Free Operating Temperature Range Packing Method Tube Tube FAN7382MX(1) FAN7382M1(1) FAN7382M1X Note: (1) Yes -40°C ~ 125°C Tape & Reel Tube Tape & Reel 1.
