Description

The IR2109(4)(S) are high voltage, high speed power

MOSFET and IGBT drivers with dependent high and

low side referenced output channels. Proprietary 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
