IR Introduces Robust AUIRS20302S 3-Phase Gate Drive IC for Automotive Applications

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

Capable of driving 6 N-channel power MOSFETs or IGBTs, the AUIRS20302S uses a bootstrap technique to supply the high-side driving circuitry. The device also features embedded deadtime and cross-conduction prevention functions and under-voltage and over-current protection with diagnostics.

Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL outputs, down to 3.3V 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 percent 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, feature an environmentally friendly, lead-free and RoHS compliant bill of materials.
