Description
The AUIRS21811S is a high voltage, high speed power MOSFET and IGBT driver with independent 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. The floating channel can be
used to drive an N-channel power MOSFET or IGBT in the high-side configuration which operates up to
600V.

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.
Recommended Operating Conditions
The Input/Output logic timing diagram is shown in Figure 1. For proper operation the device should be used
within the recommended conditions. V
S
and offset rating are tested with all supplies biased at 15V
differential.
† Logic operational for V
