FAN7383 Half-Bridge Gate-Drive IC February 2007 FAN7383 Half-Bridge Gate-Drive IC Features Floating Channel Designed for Bootstrap Operation to +600V. Typically 350mA/650mA Sourcing/Sinking Current Driving Capability for Both Channels Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VDD=VBS=15V High-Side Output in Phase of IN Signal Built-in UVLO Functions for Both Channels Built-in Common-Mode dv/dt Noise Canceling Circuit Typically Internal 330ns Minimum Dead-Time Programmable Turn-On Delay Time Control (Dead-Time) Description The FAN7383 is a half-bridge gate-drive IC with shutdown and programmable dead-time control functions for driving MOSFETs and IGBTs that operate up to +600V. Fairchild’s high voltage process and common-mode noise canceling technique give stable operation of highside 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 for both channels prevent malfunction when VDD and VBS are lower than the specified threshold voltage. Output drivers typically source/sink 350mA/650mA, respectively, which is suitable for all kinds of half and full bridge inverter. 14-SOP Applications SMPS Motor Drive Inverter Fluorescent Lamp Ballast HID Ballast 1 Ordering Information Part Number FAN7383M (1) Package 14-SOP Pb-Free Yes Operating Temperature Range Packing Method -40°C ~ 125°C Tube Tape & Reel FAN7383MX(1) Note: 1.
