Compact PDF datasheet, 15.3 KB, covering the SM5843AP1 integrated circuit. The name states only the part number with what looks like a package or variant suffix; no manufacturer or document revision is given. Small sheets like this often hold the essentials: pin functions, electrical ratings and a block or application diagram. Use it to identify signal and supply pins before probing with a multimeter or scope, and confirm the suffix on the real package matches before treating another variant as an equivalent.
