GreenFET3™ Single P-Channel Integrated Power Switch

A 33 mΩ, 1 A pFET IPS with Controlled Inrush Current in a 0.64 mm² WLCSP

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 integrated power 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 integrated power 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 Dialog’s 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.
