In this configuration, the unidirectional motor or solenoid / relay load is connected between an output (for example OUT1) and the supply (for example VM) as shown in Figure 1-1 (Passive OLD) and Figure 1-2 (Active OLD). This configuration is used for unidirectional control of loads. During the passive OLD, there is no current flow to the load. During the active OLD, the load's current flows from VM to OUT1 to GND when the low-side FET is turned ON.
