A 4 mm², 4 mΩ, 4 A Integrated Power Switch with VOUT Slew-rate Control, Current-Limiting, and Thermal Protection

Operating from a 2.5 V to 5.5 V power supply and fully specified over the -40 °C to 85 °C temperature range, the SLG59M1709V is a high-performance 4 mΩ, 4 A single-channel nFET integrated power switch with adjustable inrush current control which is achieved by adjusting the VOUT slew rate with an external capacitor. Using a proprietary MOSFET design, the SLG59M1709V achieves a stable 4 mΩ R_DSONacross a wide input/supply voltage range. Incorporating two-stage current protection as well as thermal protection, the SLG59M1709V is designed for all 0.8 V to 5.5V power rail applications. Using Dialog’s proprietary CuFET™ technology for high-current operation, the SLG59M1709V is packaged in a space-efficient, low thermal resistance, RoHS-compliant 1.6 mm x 2.5 mm STQFN package.
