Overview

Description

The SLG59M1657V is a high‑performance 8.4mΩ, 4A single‑channel nFET load switch that can operate with a 2.5V to 5.5V VDD supply to switch power rails from as low as 0.9V up to the supply voltage. The SLG59M1657V incorporates two-level overload current protection, thermal shutdown protection, and inrush current control which can easily be adjusted by a small external capacitor. Using a proprietary MOSFET design, the SLG59M1657V achieves a stable 8.4mΩ RDSON across a wide input voltage range. In addition, the SLG59M1657V’s package also exhibits low thermal resistance for high-current operation. Fully specified over the -40 °C to 125 °C temperature range, the SLG59M1657V is packaged in a space‑efficient, low thermal resistance, RoHS‑compliant 1.5mm x 2.0mm STDFN package.
