IR has introduced the AUIRS212xS family of rugged 600V, single channel high-side driver ICs for low, mid and high voltage automotive applications including general purpose automotive drives, high voltage actuators and fuel-efficient direct injection systems.

Qualified to AEC-Q100 standards, the AUIRS2123S and AUIRS2124S high speed power MOSFET and IGBT drivers offer a gate drive supply range from 10V to 20V. The output drivers feature a high pulse current buffer stage designed for minimum driver cross conduction, while the floating channel can be used to drive N-channel power MOSFETs or IGBTs in the high-side configuration operating up to 600V. Both devices feature negative voltage spike (Vs) immunity to protect the system against catastrophic events during high current switching and short circuit conditions.

“Designed specifically for automotive applications, the new ICs use a proprietary latch immune CMOS technology featuring exceptional negative Vs immunity to deliver the ruggedness and reliability essential for harsh environments and automotive under-the-hood applications,” said Henning Hauenstein, vice president of IR’s automotive products.

The AUIRS2123S features output signals in phase with the input signal while the AUIRS2124S features output signals out of phase with the input signal. Both devices provide undervoltage lockout and CMOS Schmitt-triggered inputs with pull-down.

The new ICs utilize IR’s advanced high voltage IC process which incorporates next generation high voltage level shifting and termination technology to deliver superior electrical over stress protection and higher field reliability.

 

FEATURES Floating channel designed for bootstrap operation Fully operational to +600V Tolerant to negative transient voltage – dV/dt immune Gate drive supply range from 10V to 20V Undervoltage lockout CMOS Schmitt-triggered inputs with pull-down Output in phase with input (AUIRS2123) or out of phase with input (AUIRS2124) Leadfree, RoHS-compliant Automotive qualified* * Qualification standards can be found on IR’s website www.irf.com
