GreenFET Single N-Channel Load Switch


A 125 °C-rated, 1.6 mm², 17 mΩ, 2.5 A Internally-protected Load Switch with Discharge

The SLG59M1658V is a high performance 17 mΩ, 2.5 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 SLG59M1658V incorporates two-level overload current protection, thermal shutdown protection, fast output voltage discharge, and in-rush current control which can easily be adjusted by a small external capacitor. Using a proprietary MOSFET design, the SLG59M1658V achieves a stable 17 mΩ RDSON across a wide input voltage range. In addition, the SLG59M1658V’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 SLG59M1658V is packaged in a space-efficient, low thermal resistance, RoHS-compliant 1.0 mm x 1.6 mm STDFN package.
