I have an IR2104 MOSFET half-bridge driver connected exactly as shown in an example circuit in its datasheet:
I'm using two IRGPS4067DPBF IGBTs and a 100nF bootstrap capacitor. The whole circuit including the high-side IGBT collector are running on 5VDC. SD and IN are pulled to Vcc. Yet for some reason both the high-side and low-side outputs of the driver are pulled to ground at all occasions (measured with an oscilloscope) and neither of them ever goes high no matter if IN is high or low.
I tried using a different driver yesterday (L6384) with exactly the same results, so I thought that maybe it's broken and bought a different driver today, but without any success as I explained.
What am I doing wrong?
