OK, I see that in the link you provided but it looks like it is suppose to reset itself. If not I have to figure out how to turn it back on. Also it says "• Programmable Pulse by Pulse Current Limiting" and this has me thinking, do I have to program the IC before I can use it?
The datasheet lists "inherent" regulation through pulse limiting so no programming should be necessary. You can see in the one table that lists the "shutdown" terminal that there is a range of current that either latches or unlatches the IC. Anything above 1.5 ->3.0 ma latches the circuit shut down. Anything below 1.5 ma latches the circuit open. It's not the way I would design the IC as current may fluctuate in operation and that is a narrow range of current. It is what it is.
There may be a better PWM IC with the same pinout that you could use to replace the one that is stock.
