Expanding the State-of-the-Art in System Protection Devices, Silego Announces New 125°C- rated GFET3 and HFET1 Integrated Power Switches

Addressing pcb-space-constrained applications in the industrial, in-cabin infotainment, and enterprise/embedded computing markets, these five new products include a suite of system-level protection features. In space-constrained applications, elevated operating temperatures place additional performance burdens on system protection devices. In many cases, system designers are forced to select less robust products or implement discrete, pcb-space-consuming alternatives when in-circuit ambient temperatures exceed 85°C or 105°C.

For supply-voltage applications up to 5 V, Silego announced the 8.4 mΩ/4 A SLG59M1657V, the 17 mΩ/2.5 A SLG59M1658V, and the 13 mΩ/3.5 A SLG59M1707V. In addition, the SLG59M1707V's analog current monitor output feature offers substantial system BOM cost/pcb savings by eliminating the need for an external current shunt resistor, a difference/level-shifting amplifier, and associated passive components to measure directly FET current. Depending upon the application's maximum operating current, pcb footprints range from 1.6 mm2 to 4 mm2.

For supply-voltage applications up to 24 V, Silego announced the 13.3 mΩ/4 A SLG59H1013V and the 13.1 mΩ/3.5 A SLG59H1016V, in 4.8 mm2 package sizes. Like the SLG59M1707V, both products include an analog current monitor feature, an open-drain FAULT output, and fast output voltage discharge.

Using Silego's proprietary MOSFET design IP, these extended industrial temperature range, robust integrated system protection devices maintain ultra-stable, low RDSONs across the applied input voltage range. Applying Silego's proprietary CuFET™ technology, Silego's design engineers deftly package these products in low thermal-resistance, RoHS-compliant footprints that generate low thermal gradients in these space-constrained, high-current applications.

Silego's newest additions to its industry-leading GFET3 and HFET1 product portfolio include:
