Silego Technology has announced an expansion of its state-of-the-art PFET integrated power controller portfolio with a family of self-powered, 1.6 mm², single-channel and dual-channel very low-power controllers with reverse-current protection. Designed for all high-side, 1.5 to 5.5V power rail applications, these PFET power controllers achieve an ultra-stable 23mΩ R_DSON over temperature.

Using Silego’s proprietary CuFET technology, these products can handle load currents up to 4A and exhibit low thermal resistance. The reverse-current protection feature is very useful in applications where a VOUT-to-VIN backfeed current to the VIN power source is to be avoided. Compared to other PFET load switches currently available in the market, these Silego’s controller products combine higher-performance lower R_DSON PFET structures, lower supply current operation and multiple protection features into very PCB space-efficient solutions.

Using Silego’s proprietary p-channel MOSFET design IP, these additions to its high-performance PFET integrated power switches include (4) dual-channel, 2-A devices and (1) single-channel, 4-A device:

Designed to operate over the industrial -40°C to 85°C temperature range, these new micropower, PFET integrated power control switches are available in a RoHS-compliant 1.0 x 1.6 mm package.
