AUIRS2184(4)S
Description
The AUIRS2184(4)S are high voltage, high speed power MOSFET and IGBT drivers with dependent high
and low-side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable
ruggedized monolithic construction. The logic input is compatible with standard CMOS or LSTTL output,
down to 3.3 V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver
cross-conduction. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the
high-side configuration which operates up to 600 V.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All
voltage parameters are absolute voltages referenced to COM lead. Stresses beyond those listed under "
Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only; and
functional operation of the device at these or any other condition beyond those indicated in the
“Recommended Operating Conditions” is not implied. Exposure to absolute-maximum-rated conditions for
extended periods may affect device reliability. The thermal resistance and power dissipation ratings are
measured under board mounted and still air conditions. Ambient temperature (T
A
) is 25°C, unless otherwise
specified.
