600V ICs for automotive applications

International Rectifier 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 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.
