I am using an L293DD Dual H-Bridge IC to power my DC motors. I have realized I am using inadequate heatsinks, and 1,5 times the nominal maximum current(1,8A instead of 1,2A), but the circuit is working.
The datasheet says, that this IC has overtemperature protection, but doesn't mention exact data.
My question is, can I rely on its overtemperature protection? I don't mind if the IC shuts down, when I overdrive it, but when it cools down, it should start working again.
Note: This is a prototype, I know its horrible practice, Still I want to know what can I expect, perhaps understand what is going on in more depth.
