ICs to drive MOSFET/IGBTs in automotive electronics systems

International Rectifier has introduced the AUIRS2117S and AUIRS2118S 600V ICs to e drive the power devices such as MOSFET/IGBTs in automotive applications including direct injection, and brushless DC motor drives. The high-side drivers feature very short turn-on and turn-off propagation time which drives the MOSFET or IGBT at a high frequency thus helps in shrinking system size by using smaller filtering components.

"The AUIRS2117S and AUIRS2118S expand IR's portfolio of ICs designed and qualified specifically for the automotive market. Both devices offer a reliable compact design solution essential for harsh environments and automotive under-the-hood applications," said Marzak Li, product marketing manager, IR's Automotive Products Business Unit.

The AUIRS2117S features output signals in phase with the input signal and CMOS Schmitt-triggered inputs with pull-down. The AUIRS2118S features output signals out of phase with the input signal and CMOS Schmitt-triggered inputs with pull-up. Both devices provide under-voltage lockout and offer a gate drive supply range from 10V to 20V.

The ICs ensure reliable operation by using high-voltage integrated circuit (HVIC) and latch immune CMOS technologies to offer ruggedized monolithic construction and benchmark negative voltage spike immunity. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration, operating up to 600V. The devices qualify according to AEC-Q100 standards.
