IR2235(J&S)

The  IR2235(J&S) are 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 technology enables ruggedized monolithic construction.  Logic inputs of the IR2235(J&S) are compatible with CMOS or LSTTL outputs, down to 2.5V logic. An independent opera-tional amplifier provides an analog feedback of bridge current via an external current sense resistor. A current trip function which terminates all six outputs can also be derived from this resistor. A shutdown function is available to terminate all six outputs.  An open drain FAULT signal is provided to indicate that  an over-current or undervoltage shutdown has occurred. Fault conditions are cleared with the FLT-CLR lead. The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction.  Propa-gation delays are matched to simplify use in high frequency applications. The floating channels can be used to drive N- channel power MOSFETs or IGBTs in the high side configuration which operates up to 600 volts or 1200 volts.
