Silego's 40mΩ dual-channel GreenFET3 load switch has 1.0 x 1.6 mm footprint



SLG59M1446V 40mΩ dual channel GreenFET3 load switch

Silego Technology introduced the SLG59M1446V, a 40 mΩ dual channel GreenFET3 load switch product based on Silego’s proprietary sub-micron copper power FET technology. This technology supports the world’s smallest full-featured, high efficiency power switches down to 1 x 1 mm in standard plastic packaging.

The SLG59M1446V is a full-featured dual channel load switch packaged in an 8-pin STDFN 1.0 x 1.6 mm package. Each channel can be configured and enabled independently. This device features a linear voltage ramp even under dynamic loading conditions. The ramp rate on each channel can be independently adjusted using external resistors. The device can switch power rails in the range from 1.0 V to 5.0 V, up to 1 A continuous current and 1.5 A peak current.

“The 1.0 x 1.6 mm package allows active semiconductor devices to be placed into extremely space constrained applications,” said Nathan John, Silego’s Director of Product Marketing. “The CuFET technology allows devices that are both high performance and ultra-small, compatible with standard high reliability plastic packaging.”

Standard STDFN packaging provides additional protection from ambient light and cracking so often associated with the process of handling WLCSPs. The superior mechanical design allows standard PCB manufacturing flows to handle Silego’s GreenFET devices.
