FAN73832: 625V,0.65/0.35A sink/source current, Half Bridge Gate-Drive with variable Deadtime, Shutdown protection

The FAN73832 is a half-bridge, gate-drive IC with shutdown and programmable dead-time control functions 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 Current Driving Capability for Both Channels
• Extended Allowable Negative V_S Swing to -9.8V for Signal Propagation at V_DD<=V_BS=15V
• High-Side Output in Phase of IN Input Signal
• Built-in UVLO Functions for Both Channels
• Built-in Common-Mode dv/dt Noise Canceling Circuit
• Internal 400nsec Minimum Dead-Time at R_DT=20KO
• Programmable Turn-on Delay-Time Control (Dead-Time)
