Gate Driver Shrinks Power Trains

The AUIR0815S automotive-qualified IC features an output current in excess of 10A to drive large IGBTs or MOSFETs in inverter stages for the power train of hybrid and electrical vehicles. Typical output resistance is 90 m? sink and 180 m? source. The device also features negative Vgs driving and continuous on-state capability as a result of an integrated PMOS output in parallel to the high-side pull-up NMOS. The OUTH and OUTL separated outputs allow selection of two different external resistors for charging and discharging the gate essential for controlling EMI and CdV/dT effect in high power motor driver and SMPS applications. Available in an 8-pin SOIC package, pricing for the AUIR0815S begins at $0.99 each/10,000. INTERNATIONAL RECTIFIER, El Segundo, CA. (310) 252-7726.
