Hip4081a h-bridge circuit

Webb7 juni 2024 · The MOSFETs have 1.6 nF gate-source capacitance and you have 47R gate resistors. Together this makes a rise time of around 1x CR or 75 ns yet, those MOSFETs are good for rise times that are significantly lower than this. Is there a reason? Maybe it's because the HIP4081A driver can only deliver 2.5 amps to the MOSFET gates? http://edge.rit.edu/content/P08201/public/Electrical/Reference/H-Bridge/Other/HIP4081A%20Info.pdf

Webb31 maj 2024 · As a consequence of #1, you also have no decoupling capacitors for your IC. You also do not have any for your H-bridge (your H-bridge probably draws much more current than your IC so will require much larger decoupling capacitors). Your gate drive signals on the A-side are reversed. Both of your HI input signals tied permanently to Vcc.
