Hey guys, if you look at the datasheet of Allegro's UCN5804 typical application shows 4 diodes in series from the 4 o/p's to the 4 windings with anode towards the windings and the cathode towards the chip's o/p .....
im a bit comfused with how this works.....i know the datasheet says sumthing about substrate current but this does not make much sense to me!!!
how can the o/p from the chip even reach the windings if the diode is reverse biased???
Thanks Nav
