Pin Definitions and Functions
Function
Digital control inputs IX0, IX1 for the magnitude of the current of the
particular phase. See
Input Phase 1; controls the current through phase winding 1. On
H-potential the phase current flows from Q11 to Q12, on L-potential in
the reverse direction.
Ground; all pins are connected internally.
Oscillator; works at approx. 25 kHz if this pin is wired to ground
across 2.2 nF.
Resistor
Push-pull outputs Q11, Q12 for phase 1 with integrated free-
wheeling diodes.
