International Rectifier (IR)’s AUIRS2117S and AUIRS2118S 600-V integrated circuits (ICs) are used in automotive gate drive applications including direct injection and brushless dc motor drives. Designed and qualified specifically for the automotive market, IR's AUIRS2117S and AUIRS2118S offer a reliable compact design solution suitable for harsh environments and automotive under-the-hood applications. Both high-side drivers feature very short turn-on and turn-off propagation time to drive the MOSFET or insulated gate bipolar transistor (IGBT) at a much higher frequency to shrink system size by enabling the use of smaller filtering components. The AUIRS2117S features output signals in phase with the input signal and complementary metal-oxide semiconductor (CMOS) Schmitt-triggered inputs with pulldown. The AUIRS2118S provides output signals out of phase with the input signal and CMOS Schmitt-triggered inputs with pullup. Both devices provide under-voltage lockout and offer a gate drive supply range from 10 to 20 V.
