SLG59H1009V

Overview

The SLG59H1009V is a high-performance, self-powered single N-channel NMOS load switch designed for power rails ranging from 4.5V to 22V with up to 4A continuous current. It features a stable 13.1mΩ RDSON across the input voltage range and operates within a -40°C to +85°C temperature range. The device utilizes a proprietary MOSFET design and copper pillar interconnects for low thermal resistance in an STQFN-18 package (1.6mm x 3.0mm). Key electrical parameters include a maximum operating voltage of 22V, typical on-resistance of 13.1mΩ, and output current capability of 4A.
