What the 8-SOIC footprint demands on the board
The MAX682ESA+T is a step-up charge pump in an 8-SOIC package — 0.154-inch body width, 3.90 mm, the standard narrow SOIC footprint. The scorch mark on a dead board often traces back to a shorted charge-pump cap or an input rail that dipped below the 2.7 V minimum, not the IC itself. No synchronous rectifier means the external Schottky diode takes the forward drop — budget that into the efficiency calculation at the BOM stage.
Active production and compliance paperwork
The 8-SOIC supplier device package matches the 8-SOIC case code, so the footprint is standard across multiple second-source charge-pump alternatives if you need a BOM hedge.
