Function
Error output; signals with "low" the errors: open load or short circuit
to ground of one or more outputs or short circuits of the load or
overtemperature.
Input phase 2; controls the current flow through phase winding 2.
On H-potential the phase current flows from Q21 to Q22, on
L-potential in the reverse direction.
