Silego Technology, a developer of highly configurable and cost-effective mixed signal products, has announced an expansion of its state-of-the-art pFET integrated power controller portfolio with a new 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 V to 5.5 V power rail applications, these new pFET power controllers achieve an ultra-stable RDSON over temperature. Using Silego's proprietary CuFET technology, these new products can handle load currents up to 4 A 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 new Silego's controller products combine higher-performance lower RDSON 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 new additions are 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.
