The invention relates to a circuit assembly for controlling at least two reactive loads (L1, L2, L3, L4) to be bidirectionally operated from a supply source(V0, GND), wherein a controllable direction switch (T1, T6) is associated with all loads (L1, L2, L3, L4) for each operation direction, wherein each direction switch (T1, T6) is connected to a first supply potential (V0) by means of a first connection and to a connection of the loads (L1, L2, L3, L4) that is associated with the direction switch via a respective diode (D1-D8) polarized in the conducting direction by means of a second connection. A respective controllable selection switch (T2 - T5, T7 - T10) is associated with each load (L1, L2, L3, L4) for each operation direction, wherein each selection switch (T2 - T5, T7 - T10) is connected to a connection of the load (L1, L2, L3, L4) that is associated with the selection switch by means of a first connection and to a second supply potential (GND) by means of a second connection. The direction switches (T1, T6) and selection switches (T2 - T5, T7 - T10) are formed by power transistors having inverse diodes, wherein the drain connections of the selection switches (T2 - T5, T7 - T10) are connected to the gate connections of the selection switches (T2 - T5, T7 - T10) by means of zener diodes (ZD2 - ZD5, ZD7 - ZD10). |
