IR2133/IR2135/IR2233/IR2235 Gate Driver ICs Infineon Technologies IR2133/IR2135/IR2233/IR2235 Gate Driver ICs feature three independent high side and low side referenced output channels for 3-phase applications. The Gate Driver ICs have a proprietary HVIC technology that enables ruggedized monolithic construction. The IR2133/IR2135/IR2233/IR2235 ICs have logic inputs compatible with CMOS or LSTTL outputs, down to 2.5V logic. Additionally, the devices provide an independent operational amplifier. This amplifier permits analog feedback of bridge current via an external current sense resistor.
