International Rectifier has introduced the AUIRS212xS family of rugged 600-V, single-channel high-side driver ICs for low-, mid-, and high-voltage automotive applications.

Qualified to AEC-Q100 standards, the AUIRS2123S and AUIRS2124S high-speed power MOSFET and IGBT drivers can be driven by a gate voltage ranging from 10 to 20 volts.

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 either the N-channel power MOSFET or the IGBT in the high-side configuration operating at up to 600 volts. Both devices feature negative voltage spike (Vs) and immunity to protect 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 undervoltage lockout and CMOS Schmitt-triggered inputs with pull-down.

The new ICs utilize IR's advanced high-voltage process that incorporates high-voltage, level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability.

Available in an 8-lead SOIC package, pricing for the AUIRS212xS begins at $0.72 each in quantities of 100,000 units. Production quantities are available immediately. Both devices are lead-free and RoHS compliant.
