A 1.4 mm², 18 mΩ, 2 A Load Switch with Slew-rate Control, Current-Limiting, and Thermal Protection

The SLG59M1721V is a high performance 18 mΩ, 2.0 A single-channel nFET load switch which can operate with a 2.5 V to 3.6 V VDD supply to switch power rails from as low as 0.85 V up to the supply voltage. The SLG59M1721V 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 SLG59M1721V achieves a stable 18 mΩ RDSON across a wide input voltage range and over temperature. In addition, the SLG59M1721V’s package also exhibits low thermal resistance for high-current operation using proprietary CuFET technology. Fully specified over the -40 °C to 85 °C temperature range, the SLG59M1721V is packaged in a space-efficient, low thermal resistance, RoHS-compliant 1.0 mm x 1.4 mm STDFN package.
