Data Sheet
Function
Digital control inputs IX0, IX1 for the magnitude of the current of the
particular phase.
1)
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 at leadframe 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.
Supply voltage; block to ground, as close as possible to the IC, with a
stable electrolytic capacitor of at least 47 µF in parallel with a ceramic
capacitor of 100 nF.
Error 2 output; signals with “low” the errors: short circuit to ground of
one or more outputs or over-temperature.
Push-pull outputs Q22, Q21 for phase 2 with integrated free-wheeling
diodes.
Resistor
Error 1 output; signals with “low” the errors: open load or short circuit to
+
temperature.
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.
