Abstract
Methods and apparatuses for connecting multiple loads with a common return pin in engine control module application are disclosed. Only one of the multiple loads can be connected to a power source at a time. At the high side, each load is coupled to the power source through a respective pin at a connector. At the low side, the multiple loads share a common return pin at the connector that connects the loads to the ground. When a first load is connected to the power source at the high side, a first low side driver circuit is used to connect the first load to the ground at the low side. When a second load is connected to the power source at the high side, the second low side driver circuit is used to connect the second load to the ground at the low side.
