24V, 5A, power controllers integrate control & protection into 4.8 mm²

March 07, 2016 // By Graham Prophet
Silego Technology, (Santa Clara, California) has added a family of high-voltage integrated power controllers designed for all high-side, 4.5 V to 24 V power rail applications. Using Silego’s own MOSFET design IP, these controllers are based around a power switch that presents an ultra-stable 13.3 mΩ RDS(ON) across a wide input/supply voltage range and over temperature.

Using Silego’s CuFET technology, these new products require only a 4.8 mm² footprint and exhibit low thermal resistance for high-current operation. Compared to discrete FETs currently used in high-voltage applications, the HFET1 products combine high-performance nFET structures, charge pumps, multiple protection and control circuits into small-footprint, feature-rich, single-channel products. Designed to operate over a -40°C to 85°C range, these high-voltage integrated power control switches are available in low thermal resistance packaging. Use them, the company suggests, in high voltage power-rail switching; 12V, 15V, and 20V point-of-load power distribution; IT and office equipment; and motor drives.
