I am aware of the equation in this pdf, but since these wont drive the H-bridge continuously I dont know what to use for the frequency. I am driving a motor with the H-bridge.
You control the frequency so you should know exactly what it is.
The bootstrap capacitor power cannot be used if you require DC drive from the H-bridge. Each half-bridge must be driven low frequently to 'refresh' the capacitor, or the charge will leak off and the drive to the high-side n-channel MOSFET will be compromised.
If you need to drive it high continuously you must use a different type of power such as a DC-DC converter.
