Ok I will try connecting a load the circuit and connecting Vs to the low side mosfet drain, and hopefully that will help. Though the IRS2186 I have doesn't turn on HO and LO separately, an input to HIN and LIN turns both on at the same time, as it is a part of a full Hbridge not a half bridge...
Thank you for the information, looking at the circuit of the IRS2186 it seems like the high side output will switch between Vb and Vs, which as you say shouldn't exceed 18V difference, however doesn't Vb have to be at a voltage level higher than than the H-bridge supply, as it needs to drive the...
Thank you for your replies, no I had not connected a load, as I thought I would be able to test it first. I have tried connecting Vs to ground, at which point HO then switches from 0V to 12V but since it is now referenced to ground it didn't seem like it would drive the high side mosfet? The...
I have been working with the gate drive IC IRS2186 and I have posted the recommended connections from the datasheet, with Vcc at 12V and the MOSFET high side voltage at 30V and 10µF for C2 and 1µF for C1. I can get the low side to work just fine but the high side HO always remains at 12V no...
