Pin Definitions and Functions (cont’d)

Pin No.

Function

17 (21) 1)

Inhibit input; the IC can be put on standby by low potential on this

pin. This reduces the current consumption substantially.

18 (22) 1)

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.
