Description ofs,tiiti,is xii,iiii,tit,,ss,,,,,,
The lRS2109/lRS21094 are high voltage, high ' Jit
speed power MOSFET and IGBT drivers with de- 'tiii''''' "fi'jiiliiiisk
pendent high- and Iow-side referenced output ta
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 pulse current
buffer stage designed for minimum driver cross-con-
duction. The floating channel can be used to drive 8 Lead PDIP
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.
