Motor vehicle ICs

International Rectifier has introduced the AUIRS212xS family of rugged 600 V, single-channel high-side driver ICs for low-, mid- and high-voltage motor vehicle applications, including general-purpose 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 10 to 20 V.

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 600 V.

The devices feature negative voltage spike immunity to protect the system 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 undervoltage lockout and CMOS Schmitt-triggered inputs with pull-down.
