GreenFET™ Ultra-Low RDSON Load Switch Selector Guide
■Dialog's GreenFET family of high-performance load switches are designed and optimized for all high-side power rail control applications from 0.25V to 5.5V where the load currents range from 1A to 9A. Using Dialog’s proprietary MOSFET design, all GreenFET load switches achieve ultra-stable RDSON across wide input and supply voltage ranges. Combining Dialog's proprietary MOSFET IP and advanced assembly techniques, these advanced state-of-the-art products are available in ultra-small pcb footprints from 0.56mm2to 4mm² and exhibit low thermal resistances for high-current operation.
■Compared to discrete GreenFET circuit implementations, Dialog’s GreenFET products combine high-performance nFET or pFET structures, high-current handling capability, charge pumps, as well as multiple protection and control circuits into space-efficient single-and dual-channel products. The combination of all these advanced features directly results in BOM (bill-of-material) component and cost reductions as well as increasing system reliability and reduced board size.
■All of Dialog’s GreenFET low-voltage load switches are designed and fully characterized over the commercial (0°C to 70°C), extended commercial (-20°C to 70°C), industrial (-40°C to 85°C), or extended industrial (-40°C to 125°C) temperature range. Consistent with generating very low thermal gradients, Dialog integrated power control switches are availablein low thermal resistance, STDFN/STQFN RoHS-compliant packaging or wafer-level chip scale packaging (WLCSP).
