I do not understand what the High Side Drive really is doing?
It says on page 8 that high side drive can protect from being "energized"... what is energized? The way I see the circuit is that if the load is to high(low resistance) then there will be a lot of current and then the circuitry can sense this and turn use some type of circuit limiting method?
If thats right then I do not get the low side drive. Looks to me, with the circuit that is shown, there is no difference. Cause it just shows that the load is shorted before the switch but I see the same can happen with the high side(if it is shorted to ground before the switch in the high side drive circuit)? Although is the current limiting is inside the circuit then I do see a different... i.e., no way to short before the circuit limiting circuitry.
Is this making sense?
Thanks, Jon
