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.

Absolute Maximum Ratings
Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. TA=25C unless otherwise specified.
