1200 V, 0.25 A Three Phase Gate Driver IC IR2235 with over current
protection, fault reporting, OPAMP, and shutdown

The IR2133IR2135/IR2233IR2355 (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 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. 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 under voltage 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. Propagation 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.

Model performance :
