Description
The IRS2104 is a high voltage, high speed power
MOSFET and IGBT driver with dependent high- and low-
side referenced output channels. Proprietary HVIC and
8 Lead SOIC
8 Lead PDIP
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 from 10 V 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. The thermal resistance and power dissipation ratings are
measured under board mounted and still air conditions.
