The SLG59H1005V is a high‑performance, self‑powered 50 mΩ NMOS load switch with back-to-back reverse‑current blocking designed for all 4.5 to 22 V power rails up to 3 A. Using a proprietary MOSFET design, the SLG59H1005V achieves a stable 50 mΩ RDSON across a wide input voltage range. In combining novel FET design and copper pillar interconnects, the SLG59H1005V package also exhibits a low thermal resistance for high‑current operation. Designed to operate over a -40 °C to 85 °C range, the SLG59H1005V is available in a low thermal resistance, RoHS‑compliant, 1.6 mm x 3.0 mm STQFN package.
