IR2233/IR2235 MOSFET & IGBT Drives Infineon Technologies IR2233/IR2235 MOSFET and IGBT Drives feature three independent high- and low-side referenced output channels for 3-phase applications. Proprietary HVIC technology enables ruggedized monolithic construction. Logic inputs are compatible with CMOS or LSTTL outputs, down to 2.5V logic. An independent operational amplifier provides an analog feedback of bridge current via an external current sense resistor.
