GreenFET Single N-Channel Load Switch


A 125 °C-Rated, 3 mm², 8.4 mΩ, 4 A Internally-protected Load Switch

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