Logic and power ground +/- 5 V offt.
•Internal 540 ns deadtime, and programmable up to 5 µs with one external R DT resistor (IRS21094)•Lower di/dt gate driver for better noi immunity •Shutdown input turns off both channels.Description
The IRS2109/IRS21094 are high voltage, high speed power MOSFET and IGBT drivers with de-pen dent hig h- and low -side referenced output channels. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with stan-dard CMOS or LSTTL output, down to 3.3 V logic.The output drivers feature a high pul current buffer stage designed for minimum driver cross-con-duction. The floating channel can be ud 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 param-eters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are measured under board mounted and still air conditions.
