Silego Introduces New GFET3 Integrated Power Switches and Advances the State-of-the Art in Low RDSON, High-Current Performance

Silego Technology, a developer of highly configurable and cost-effective mixed signal products, today announced an expansion of its state-of-the-art portfolio with a new family of high-performance, GFET3 integrated power switches. Operating from 2.5 V to 5.5 V supplies, these new single-channel GFET3 nFET integrated power switches were designed for all high-side, 0.8 V to 5.5 V power rail applications. Using Silego’s proprietary MOSFET design IP, these new feature-rich integrated power switches maintain an ultra-stable 4 mΩ RDSON across the applied input voltage range and over temperature. Applying Silego’s proprietary CuFET™ technology, Silego’s design engineers deftly packaged these new products in low thermal-resistance footprints for high-current operation.

The SLG59M1714V – the flagship of these four new products – incorporates a 15-mΩ, back-to-back reverse block nFET arrangement for those applications where VOUT-to-VIN backfeed current to the VIN power source is to be avoided. In addition, the SLG59M1714V’s IOUT 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.

Designed to operate over a -40°C to 85°C range, all four products are available in RoHS-compliant STQFN-16 packaging.

Silego’s newest additions to its industry-leading GFET3 products include:

Key features included in this new family of high-performance, GFET3 high-current power control products are:

• High-performance, low-leakage nFET MOSFETs
  • Non reverse block: 4 mΩ
