Description
Operating from a 2.5V to 5.5V power supply, the SLG59M1736C is a self‑powered, high‑performance 33mΩ, 2.2A single-channel pFET load switch with a controlled VIN inrush current profile. The SLG59M1736C’s low supply current and controlled VIN inrush current profile make it an ideal pFET load switch in small form factor personal health monitor and watch applications. Using a proprietary MOSFET design, the SLG59M1736C achieves a low RDSON across the entire input voltage range. Through the application of proprietary technology, the SLG59M1736C’s can be used in applications up to 2.2A with a very‑small 0.64mm² WLCSP form factor.
