Description
The IR2104/IR21044 are high voltage, high speed
power MOSFET and IGBT drivers with dependent high 8 Lead SOIC
and low side referenced output channels. Proprietary IR2104S 14 Lead SOIC
IR21044S
HVIC and latch immune CMOS technologies enable
ruggedized monolithic construction. The logic input is
compatible with standard CMOS or LSTTL output. 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 configura- 8 Lead PDIP 14 Lead PDIP
tion which operates from 10 to 600 volts. IR2104 IR21044

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.
