International Rectifier, IR ® (NYSE:IRF), a world leader in power management technology, today introduced the automotive-qualified AUIRB24427S high current dual low-side driver IC for Switched Mode Power Supply (SMPS) applications used in Hybrid Electrical Vehicles (HEV), Electric Vehicles (EV), and high power industrial converters. The AUIRB24427S features very high output current in excess of 6A per channel across the full temperature range and is designed to drive large IGBT and MOSFET gates in modules or discrete packages. Due to the device’s extremely low output impedance in turn-on and turn-off mode, power losses are also very low, allowing operation in harsh and high temperature environments such as HEV power supply stages as a primary or secondary side driver. “Housed in a simple PSOIC-8N package and featuring ultra-low power dissipation, the AUIRB24427S solves the problem of effectively driving large size IGBTs and MOSFETs used in high power SMPS applications and provides a smaller, simpler and more robust solution than existing discrete solutions currently available in the market,” said Davide Giacomini, Director of Product Management and Applications, IR’s Automotive Products Business Unit. The AUIRB24427S is available in a thermally enhanced PSOIC-8N package that delivers much higher thermal dissipation compared to standard DIL SMD packages enabling operation at a significantly higher ambient temperature. Additionally, the rail-to-rail output stage, using P-Channel MOSFETs in the high-side allows low internal dropout voltage to reduce power dissipation. The AUIRB24427S also features maximum output resistance of 650 mOhm sink and source at 125°C. More information is available at http://www.irf.com/press-room/press-releases/nr140821 Availability and Pricing Pricing for the AUIRB24427S begins at US $0.78 each in 10,000-unit quantities. Production orders are available immediately. The automotive-qualified device is lead-free and RoHS compliant. Prices are subject to change.
