Keywords:automotive? driver IC? 600V AUIRS212xS family?

From International Rectifier (IR) comes 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.

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 under-voltage lockout and CMOS Schmitt-triggered inputs with pull-down. The new ICs utilise 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.
