IR's new AUIRS212xS family driver IC for automotive applications

International Rectifier introduced the AUIRS212xS family of single channel driver ICs for low, mid, and high-voltage automotive applications including general purpose automotive drives, high-voltage actuators and fuel-efficient direct injection systems.

The new devices available in the new family are AUIRS2123S and AUIRS2124S, which can be used to drive high-speed power MOSFET and IGBT.

The output drivers of the device 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.
The features include:

1. Offers a gate drive supply range from 10V to 20V.
2. Both devices feature negative voltage spike immunity to protect the system against catastrophic events during high-current switching and short circuit conditions.
3. The AUIRS2123S features output signals in phase with the input signal while the AUIRS2124S features output signals out of phase with the input signal.
4. Both devices provide under-voltage lockout and CMOS Schmitt-triggered inputs with pull-down.

International Rectifier says that the new ICs utilize 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.

Package: 8-lead SOIC package,

Price: for AUIRS212xS begins at US$0.72 each in quantities of 100K units.
