  1. AUIRS20302S 3-Phase Gate Drive IC AUTOMOTIVE HOME PAGE The automotive qualified AURS20302S three-phase gate driver IC is designed for 12V, 24V and 48V vehicle applications including high-voltage air conditioner compressors, pumps, BLDC motor drives up to 600W and high-voltage motor drives. DATASHEET PRESS RELEASE • Advantages • The AUIRS20302S targets 12V, 24V and 48V boardnet automotive, and 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. • The AUIRS20302S is capable of driving 6 N-channel power MOSFETs or IGBTs using a bootstrap technique to supply the high-side driving circuitry and also features embedded deadtime and cross-conduction prevention functions and under-voltage and over-current protection with diagnostics. • Features • 3-Phase Gate Driver for 24V and higher drives • Under-voltage lockout for all channels • Cross-conduction prevention logic • High voltage pre-regulator MOSFET • Power-on reset architecture • FAULT detection and reset • Current sense comparator • Over-current blanking time • 3.3V logic compatible • Matched propagation delay for all channels • Fully operational up to +200V • Floating channels for bootstrap operation • High negative transients immunity • Pre-regulated supply line for uP • Automotive qualified • Lead-free, RoHS compliant HI-RES GRAPHIC September 2012 September 2012
