Description
The SLG59M1658V is a high-performance 17mΩ, 2.5A 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 SLG59M1658V incorporates two‑level overload current protection, thermal shutdown protection, fast output voltage discharge, and inrush current control which can easily be adjusted by a small external capacitor. Using a proprietary MOSFET design, the SLG59M1658V achieves a stable 17mΩ RDSON across a wide input voltage range. In addition, the SLG59M1658V’s package also exhibits low thermal resistance for high‑current operation. Fully specified over the -40 °C to 125 °C temperature range, the SLG59M1658V is packaged in a space-efficient, low thermal resistance, RoHS‑compliant 1.0mm x 1.6mm STDFN package.
