| Feb 9, 2021 at 12:57 | comment | added | jeremiah | @fifi_22 Thanks. I see the problem with bootstrap capacitance and may use charge pump set-up. I have a basic schematic from 'circuit digest' which may be enough; but if I need more guidance, I'll ask here again. You're very kind. | |
| Feb 8, 2021 at 18:12 | comment | added | fifi_22 | If You arleady got this driver - thats different thing. IR2110 migh be ok, but the slow switching times moght be a problem (not enough bootstrap capacitance). I suggest You building DIY version of driver (with charge pump). I can provide You schematic if You want. | |
| Feb 8, 2021 at 16:44 | comment | added | jeremiah | @fifi_22 Continuous 12V supply. Do you know of any prefabricated H-Bridge modules with the IRF1404 or similar? The module I have already, for which I'm trying to find a right gate driver, is Vincotech; with IGBTs, rated for 75A, flyback diodes incorporated etc.; and at the moment, am considering using IR2110 hi/lo drivers on it. | |
| Feb 8, 2021 at 16:05 | comment | added | fifi_22 | If these values are those in question ( 12V, few Hertz frequency) You can use IRF1404 or similar fets with sufficient heatsink. | |
| Feb 8, 2021 at 16:00 | comment | added | fifi_22 | @jeremiah These voltage spikes should be cached by flyback diodes placed antiparallel to the mosfets (I would also suggest snubbers across them). 60A is significant current, but depending of Your supply voltage, IRF1404 might be sufficient. Please provide more info (voltage, continous or just peak drive...) | |
| Feb 8, 2021 at 15:51 | comment | added | jeremiah | @fifi_22 Can you suggest any such MOSFETs capable of controlling 60A through an H-Bridge intended to facilitate reversal of that current through coils; so generating very large voltage spikes? | |
| Jan 26, 2021 at 13:46 | comment | added | winny | At only 12 V, you can probably cheat and use a capable driver directly. IXYS IXD609 comes to mind. You do need to pump up a supply 10+ V above your 12 Vdc though. | |

| Jan 25, 2021 at 20:54 | comment | added | jeremiah | I needed a prefabricated H-Bridge module and that's all I could find. It still should function at 12V, right. I already have what I think is a suitable high-side gate driver [ucc5390 from TI], but without technical experience wondered whether a full bridge driver might fit the scenario better. | |
