IR’s Automotive-Qualified AUIRS2117S and AUIRS2118S Deliver Reliable Compact Solution

International Rectifier, IR, a world leader in power management technology, today introduced the AUIRS2117S and AUIRS2118S 600V ICs for automotive gate drive applications including direct injection, and brushless DC motor drives.

The AUIRS2117S and AUIRS2118S high-side drivers feature very short turn-on and turn-off propagation time to drive the MOSFET or IGBT at a much higher frequency to shrink system size by enabling the use of 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 new ICs feature proprietary high-voltage integrated circuit (HVIC) and latch immune CMOS technologies to offer ruggedized monolithic construction and benchmark negative voltage spike immunity for reliable operation even under extreme switching conditions and short circuit events. 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 are qualified according to AEC-Q100 standards, feature an environmentally friendly, lead-free and RoHS compliant bill of materials, and are part of IR’s automotive quality initiative targeting zero defects.
