| Nov 2, 2022 at 20:24 | comment | added | EmeraldMonk | Sorry about, I forgot to invert the IC when i updated it in the schematic. The driver in the PCB is placed as you have said. HIN and LIN on the right and the HO and LO on the left of the respective IC. I will update the schematics and edit the image in the post. | |
| Nov 2, 2022 at 20:03 | comment | added | John Birckhead | Oops - I should have said Output N on the RIGHTMOST IC. | |

And, "Output P" should be tied to both HIN and /LIN on the leftmost IC, since /LIN is inverted for you in the IC. "Output N" (assuming it is the inverse of Output P) should then go into both HIN and /LIN on the leftmost IC. | |

| Nov 2, 2022 at 13:44 | comment | added | EmeraldMonk | I Replaced the MOSFET driver and now i have the "SAME" output waveform on both sides. So i guess the MOSFET driver was shot. How would you calculate the bootstrap Capacitor? as i plan to drive the circuit at 100kHz. | |
