Operating from a 2.5 V to 5.5 V power supply, the SLG59M1730C is a self‑powered, high‑performance 33 mΩ, 1.0 A single-channel pFET load switch with a controlled VIN inrush current profile. The SLG59M1730C’s low supply current and controlled VIN inrush current profile makes it an ideal pFET load switch in small form-factor personal health monitor and watch applications. Using a proprietary MOSFET design, the SLG59M1730C achieves a low RDSON across the entire input voltage range. Through the application of proprietary CuFET technology, the SLG59M1730C’s can be used in applications up to 1 A with a very-small 0.64 mm² WLCSP form factor.
