Overview

The SLG59H1128V is a high‑performance, self‑powered, 13.1mΩ NMOS load switch designed for all 4.5V to 22V power rails up to 5A. Using a proprietary MOSFET design, the SLG59H1128V achieves a stable 13.1mΩ RDSON across a wide input voltage range. Combining novel FET design and copper pillar interconnects, the SLG59H1128V package also exhibits a low thermal resistance for high‑current operation. Designed to operate over a -40 °C to 85 °C temperature range, the SLG59H1128V is available in a low thermal resistance, RoHS‑compliant, 1.6mm x 3.0mm STQFN package.

  2. RSET less than 1A

    In application with SLG59H1128V, Can I have RSET value in 0.75A for Active Current Limit? According to datasheet there's no statement for less than 1A of current limitation.
