Help understanding diode function in bootstrap half bridge gate driver circuit

I am working with a bootstrapped half bridge gate driver and I am wondering if anyone knows what function D24 is performing in the attached image? I can't find this specific diode placement in any of the other circuits that I have found online. Thanks.

You are not using the IC as a half bridge driver but as a one-sided mosfet driver (you are not using the LO or Low Side Output). You are driving a motor which is inductive and liable to generate spikes of voltage. D7 and D8 will catch negative spikes, I would guess that D24 is there to catch any positive spikes generated by the motor - it will short them to the high output derive line. Anyone got any better ideas?

Cool.
