Abstract: A circuit, comprising, a first high-side switch and a second high-side switch each receiving a source voltage, a first low-side switch and a second low-side switch, a first application specific integrated circuit (ASIC) connected to the first high-side switch and the first low-side switch, and a second ASIC connected to the second high-side switch and the second low-side switch, wherein the switches are connected to form an H-bridge circuit to generate a drive current, and wherein the first and second ASICs control the switches in a synchronized manner to cause current to flow through a load in one of a first direction and a second direction.
