Description
IR2181/IR2183/IR2184 Feature Comparison
The IR2181(4)(S) are high voltage,
high speed power MOSFET and IGBT
drivers with independent high and low
side referenced output channels. Pro-
prietary HVIC and latch immune
CMOS technologies enable rugge-
dized monolithic construction. The
logic input is compatible with standard
CMOS or LSTTL output, down to 3.3V 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 volts.

Absolute Maximum Ratings
Absolute maximum ratings indicate sustained limits beyond which damage to the device may occur. All voltage param-
eters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured
under board mounted and still air conditions.
