| FAN73832 Half-Bridge Gate-Drive IC September 2006 FAN73832 Half-Bridge Gate-Drive IC Features Floating Channel 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 Input Signal Built-in UVLO Functions for Both Channels Built-in Common-Mode dv/dt Noise Canceling Circuit Internal 400nsec Minimum Dead-Time at RDT=20K Programmable Turn-on Delay-Time Control (Dead-Time) Description 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.

Normal Operating Consideration The FAN73832 is a single PWM input, half-bridge, gatedrive IC with programmable dead-time and shutdown functions. The dead-time is set with a resistor (RDT) at the DT/SD pin. The wide dead-time programming range provides the flexibility to optimize drive signal timing for a selection of switching devices (MOSFET or IGBT) and applications. The turn-on time delay circuitry (Dead-Time) accommodates resistor values from 20k to 200k with a dead-time proportional to the RDT resistance. If the DT/SD pin voltage decreases below 1.2V in the normal operation, the IC enters shutdown mode. The external dead-time setting resistor (RDT) is at least above 20K for normal operation in typical applications. 3. Layout Consideration For optimum performance of the high- and low-side gate drivers, considerations must be taken during printed circuit board (PCB) layout. 3.1 Supply Capacitors If the output stages are able to quickly turn-on a switching device with a high value of current, the supply capacitors must be placed as close as possible to the device pins (VDD and GND for the ground-tied supply, VB and VS for the floating supply) to minimize parasitic inductance and resistance. 3.2 Gate Drive Loop Current loops behave like an antenna, able to receive and transmit noise. To reduce the noise coupling/emission and improve the power switch turn-on and off performances, gate drive loops must be reduced as much as possible. 2. Under Voltage Lockout (UVLO) The FAN73832 has an under-voltage lockout (UVLO) protection circuit for high- and low-side channels to prevent malfunction when VDD and VBS are lower than the specified threshold voltage. The UVLO circuitry monitors the supply voltage (VDD) and bootstrap capacitor voltage (VBS) indepently. 3.3 Ground Plane Ground plane must not be placed under or nearby the high-voltage floating side to minimize noise coupling.
