Both the high-side and low-side power MOSFETs are built into the silicon monolithic integrated circuit, reducing the need for external components.
They stamped "9e102" on the crate in a hurried hand—black ink bleeding into fiber—an impersonal label that would outlive the men who first used it. The warehouse smelled of oil and ozone, a place where wires coiled like sleeping serpents and discarded schematics crinkled under steel-toed boots. For most, 9e102 would have been just another part number, a box to be filed away under inventory codes and supply logs. For Mara, it was the start of a question. 9e102 datasheet
