FAN73833: 625V, 3.3/5V input logic compatible, 0.65/0.35A sink/source current, Half Bridge Gate-Drive with fixed Deadtime

The FAN73833 is a half-bridge gate-drive IC for 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 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 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 inverters.

Features

• Floating Channel for Bootstrap Operation to +600V
• Typically 350mA/650mA Sourcing/Sinking CurrentDriving Capability for Both Channels
• Extended Allowable Negative V_S Swing to -9.8V forSignal Propagation at V_DD=V_BS=15V
• 3.3V and 5V Input Logic Campatible
• Outputs in Phase with Input Signals
• Built-in UVLO Functions for Both Channels
• Built-in Shoot-Through Prevention Circuit
• Built-in Common-Mode dv/dt Noise Canceling Circuit
• Internal Dead-Time: 400ns Typical
