I am trying to determine whether the SN754410 motor drivers will support
two small DC motors. (without killing the IC's or motor) Or will I need to
add a power amplification circuit.
The motors are rated @ 6v ?A. Test show that they pull 0.35A loaded and
1.5A lock rotor. Is this within the scope of the integrated hbridge of the
Handy board or will I "release the magically smoke" from the chips?
I have looked at the chips white papers for temp/current derating. (I feel
a little lost, trying to interpret the info.) :] I would appreciate some
help in determining how to derate the chips due to temperature.
Hitting on the same thread can anyone tell me the power rating for these
chips.
Thanks,
Trevor Batts

| if the worst-case current is 1.5A, you're probably OK -- the SN754410's have thermal protection for over-current conditions. they're rated for an amp continuous, so you're not too far out of bounds. one cause for concern is if the 1.5A measure is (...)
