The automotive qualified AUIRS2334S 600V IC suits threephase inverterized motor drive applications such as HV compressors and fans. The AUIRS2334S features an advanced input filter to improve the input/output pulse symmetry of the signals processed by the device. Other key features include integrated fixed deadtime protection circuitry, shoot-through protection circuitry and under-voltage lockout protection on both the VCC low-side and all VBS high-side floating power supplies. The new device is also fully characterized for negative transients on the switching node that may occur during normal operation and protection mode.
The automotive qualified IC uses proprietary HVIC and latch immune CMOS technology to enable ruggedized monolithic construction. The logic inputs are compatible with CMOS or LSTTL outputs, down to 3.3 V. The output drivers feature a high pulse current buffer stage for minimum driver cross-conduction. The floating channel can be used to drive n-channel power MOSFETs or IGBTs in the high-side configuration up to 600 V. (From $1.30 ea/10,000 — available now.)
