Function
Supply voltage; block to ground, as close as possible to the IC, with
a stable electrolytic capacitor of at least 10 F in parallel with a
ceramic capacitor of 220 nF.
Logic supply voltage; either supply with 5 V or connect to +
across a series resistor. A Z-diode of approx. 7 V is integrated. In both
cases block to ground directly on the IC with a stable electrolytic
capacitor of 10 F in parallel with a ceramic capacitor of 100 nF.
Push-pull outputs Q22, Q21 for phase 2 with integrated free
wheeling diodes.
Resistor
Inhibit input; the IC can be put on standby by low potential on this
pin. This reduces the current consumption substantially.
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.
