I'm in the process of bringing up a new design using the L6388E gate drivers. However, I've run into a stumbling block. Hopefully its something stupid in the design, but I'm at a loss: was wondering if anyone has any ideas?
I'm applying constant voltage to the HIN pin, but getting nout out on the gate line. All the other voltages are reading good, however. Cext calculations for these FETS come out at 8.3nF: so that 100nF bootstrap should be gross overkill. Voltage readings appended to the schematic below.
