Hi Ben,
Thank you for reaching out! It sounds like you will want to implement charge pump circuitry to help keep the boot cap charged. TI has a tech article available that helps explain the process for implementing a charge pump: Link . I am unaware of…
Hello Richard, really thanks.
Ok UCC27288 for my application so I can design the boot diode.
About DC BULK Capacitor (or called also DC-Link Capacitor), could you tell me if you have a guidelines or application notes to properly size this capacitor given…
Hi Damian,
It is not recommended to have large difference in voltage between the device and h-bridge. I suggest looking into the UCC27288 half-bridge high voltage driver as an alternative solution to using the DRV8701. The UCC27288 does not have OCP which…
