22V, 13.1mOhm, 4A Integrated Power Switch

Silego has added the SLG59H1009V, a high-performance, self-powered 13.1mΩ NMOS power switch designed for all 4.5- to 22-V power rails up to 4A. Using a proprietary MOSFET design, the SLG59H1009V achieves a stable 13.1mΩ RDSON across a wide input/supply voltage range and over temperature. Using Silego's proprietary CuFET™ technology, the SLG59H1009V package also exhibits a low thermal resistance for high-current operation.

Designed to operate over a -40 to +85 degrees range, the SLG59H1009V is available in a low thermal resistance, RoHS-compliant, 1.6 x 3.0 mm STQFN package. Applications are expected to include: power-rail switching, multifunction printers, large-format copiers, telecommunications equipment, high-performance computing (including 5V, 9V, 12V, and 20V point-of-load power distribution), and motor drives.

Features include: Maximum Continuous Switch Current of 4A; Automatic nFET SOA Protection; High-performance MOSFET Switch (RDSON of 13.1 mΩ at VIN = 22 V; ΔRDSON/ΔVIN under 0.05 mΩ/V; ΔRDSON/ΔT under <0.06 mΩ/ degree C); 4-Level, Pin-programmable VIN Overvoltage Lockout; Capacitor-programmable Inrush Current Control; Two-stage Current Limit Protection (Resistor-programmable Active Current Limit and Internal Short-circuit Current limit); Open Drain FAULT Signaling; MOSFET Current Analog Output Monitor: 10 μA/A; Fast 4 kΩ Output Discharge; and Pb-Free / Halogen-Free / RoHS Compliant Packaging.
