If the IC has a cutout of some sort,
then you are more likely to see it just stop as oppose to destroy
itself though.

Yes, the driver IC is current-limited to about 500mA (and thermal limited too),
so it is very hard to destroy!


Now the other question is that what other side effects are likley from
the under-voltage from rechargeables? If power levels were just low
enough to under power the h8 or its peripheral components - is there
not a potential for instability and resets? Maybe some of this should
be tested on an RCX, although I will admit to being a little reluctant
to try stuff like this on one of my own.

I have used NiMH batteries a lot on RCX, the only adverse effect I noticed is
that the power available on motors is nearly halved.

(...) I have not seen them on the RCX, but I have on other devices, where power transisotrs have died. Its all to do (I think) with the characteristics under load, and the fact that larger spikes in current may occur with rechargeables. If the IC (...) (18 years ago, 21-Jul-06, to lugnet.robotics)
