HFET1™ High-Voltage Integrated Power Control Switch

A team of engineers is ready to answer your questions

A Self-powered, 24 V, 13 mΩ / 5 A HFET1 Integrated Power Switch with VIN(OVLO) Disabled

The SLG59H1019V is a high-performance 13 mΩ NMOS power switch designed to control 4.5 V to 25.2 V power rails up to 5 A. Using a proprietary MOSFET design, the SLG59H1019V achieves a stable 13 mΩ RDSON across a wide input voltage range. In combining novel FET design and copper pillar interconnects, the SLG59H1019V package also exhibits a low thermal resistance for high-current operation. Designed to operate over a -40°C to 85°C range, the SLG59H1019V is available in a low thermal resistance, RoHS-compliant, 1.6 x 3.0 mm STQFN package.
