International Rectifier AUIRS20302S three-phase gate drive IC for automotive applications

International Rectifier AUIRS20302S is a three-phase gate driver IC for 12, 24 and 48 V vehicles. Applications include high-voltage air conditioner compressors, pumps, BLDC motor drives up to 600 W and high-voltage motor drives.

The AUIRS20302S targets 12, 24 and 48 V boardnet automotive platforms operating at voltages up to 200 V maximum. It features an external pre-regulator to generate its own supply voltage to ensure that the gate drives do not exceed 17 V even during load dump conditions. The pre-regulator VPR pin can also supply the surrounding system components if the total consumption does not exceed 100 mA.

The AUIRS20302S is a robust three-phase gate driver tailored specifically for car and truck applications ranging from 12 to 48 V. It is capable of driving six N-channel power MOSFETs or IGBTs using a bootstrap technique to supply the high-side driving circuitry. The device also features embedded deadtime and cross-conduction prevention functions and undervoltage and overcurrent protection with diagnostics.

Proprietary HVIC and latch immune CMOS technologies enable monolithic construction. The logic input is compatible with standard CMOS or LSTTL outputs, down to 3.3 V logic. The output driver features a high pulse current buffer stage designed for minimum driver cross-conduction. Propagation delays are matched to simplify use in high frequency applications.

IR’s automotive-grade IC products are subject to dynamic and static part average testing combined with 100% automated wafer level visual inspection as part of IR’s automotive quality initiative targeting zero defects. The devices are qualified according to AEC-Q100 standards and feature an environmentally friendly, lead-free and RoHS-compliant bill of materials.
