    Hello,Dear I connected the IR21362 as follows but I am not succeeding to output an signal from it;the configuration pins are connected as follows

    Pin 8:FAULT:Not connected
    pin9:ITRIP not connected
    pin 10:EN-----------------VCC
    Pin11:RCIN:resistor and capacitor added as indicated in the datasheet of the component
    pin12:VSS------------------Gnd
    pin13:COM-----------------Gnd

    could you suggest how I may connected this component,it gives no signals(at least the LO may be obtained)but I don`t get them

    Please help

    How do you have them connected. Half bridge or full bridge, the bottom mosfet must be on and the top PWM signal for the bootstrap to charge.

    I have not yet connectedthe IGBT bridge but I thought I can even get the signal at LO output even if the low IGBTs are not yet connected!!

    Please help
