I tried to use the IR2153 to run a half bridge using two n-channel
mosfets as in the circuit diagram on the first page of the data sheet,
and it didn't work.
I discovered that HO only sinks, it does not source.
LO works; it sources and sinks, and the cap for Vb does take a charge.
I found this out by slowing the timing down to about one hertz and
using grain-of-wheat lamps to see what the outuputs were doing.
Same thing happened with both chips that I tried.
Has anyone used the IR2153, and what do you have to do to get the high
side drive to work?
