FAN73932MX

FAN73932 — Half-Bridge Gate Drive IC June 2009 FAN73932 Half-Bridge Gate Drive IC Features Floating Channel for Bootstrap Operation to +600V Typically 2.0A/2.0A Sourcing/Sinking Current Driving Capability Extended Allowable Negative VS Swing to -9.8V for Signal Propagation at VBS=15V High-Side Output in Phase of IN Input Signal 3.3V and 5V Input Logic Compatible Matched Propagation Delay for Both Channels Cycle-by-Cycle Edge-Triggered Shutdown Function Built-in UVLO Functions for Both Channels Built-in Common-Mode dv/dt Noise Canceling Circuit Internal 400ns Minimum Dead-Time Description The FAN73932 is a half-bridge, gate-drive IC with shutdown and dead-time functions which can drive highspeed MOSFETs and IGBTs that operate up to +600V. It has a buffered output stage with all NMOS transistors designed for high pulse current driving capability and minimum cross-conduction. Fairchild’s high-voltage process and common-mode noise canceling techniques provide stable operation of the high-side driver under high dv/dt noise circumstances. An advanced level-shift circuit offers high-side gate driver operation up to VS=-9.8V (typical) for VBS=15V. The UVLO circuit prevents malfunction when VDD and VBS are lower than the specified threshold voltage. Applications High-Speed Power MOSFET and IGBT Gate Driver Induction Heating High-Power DC-DC Converter Synchronous Step-Down Converter Motor Drive Inverter The high-current and low-output voltage drop feature makes this device suitable for all kinds of half- and fullbridge inverters, like motor drive inverter, switching mode power supply, induction heating, and high-power DC-DC converter applications. 8-SOP Ordering Information Part Number FAN73932M FAN73932MX Package 8-SOP Operating Temperature Range -40°C to +125°C Eco Status RoHS Packing Method Tube Tape & Reel For Fairchild’s definition of Eco Status, please visit: http://www.fairchildsemi.com/company/green/rohs_green.html. © 2008 Fairchild Semiconductor Corporation FAN73932 • Rev. 1.0.0 www.fairchildsemi.com FAN73932 — Half-Bridge Gate Drive IC Typical Application Diagrams +15V Up to 600V PWM IC Control PWM Shutdown 1 IN VB HO VS VDD 8 2 SD COM LO 7 DBOOT 6 CBOOT 3 Load +15V RBOOT 4 5 Figure 1.
