IRS2334SPbF/MPbF
Description
The IRS2334 is a high voltage, high speed power MOSFET and IGBT driver with three independent high side
and low side referenced output channels for 3-phase applications. Proprietary HVIC and latch immune CMOS
technology enables ruggedized monolithic construction. Logic inputs are compatible with CMOS or LSTTL
outputs, down to 3.3 V. The output drivers feature a high pulse current buffer stage designed for minimum
driver cross-conduction. Propagation delays are matched to simplify use in high frequency applications. The
floating channel can be used to drive N-channel power MOSFETs or IGBTs in the high side configuration up
to 600 V.
