Silego Technology's Power Division has announced the Nanopower load switch family that includes two devices. The SLG59M1470V supports up to 6A loads and the SLG59M1460V supporting up to 2A loads. The firm's proprietary subµm copper power FET technology supports the world's smallest full-featured, high efficiency power switches down to 1 x 1mm in standard plastic packaging, stated the company.

Nanopower load switches support very fast power rail switching down to 9.5μs. This fast switch-on characteristic allows any sub-system to be powered quickly while providing power isolation when off. When enabled the SLG59M1470V only consumes 35nA in active mode. The ultra-low power consumption during sleep mode and low Rds(ON) performance during active mode significantly increases battery life.

SLG59M1470V is packaged in a 9 pin, 1.5 x 2.mm STDFN package. The device can switch power rails down to 1V. The Rds(ON) of the SLG59M1470V is rated at 7.4mΩ.

SLG59M1460V is packaged in an 8 pin, 1 x 1.6mm STDFN package. The device can switch power rails down to 1V. The Rds(ON) of the SLG59M1460V is rated at 21.3mΩ.

Target applications of the devices include tablets, smartphones, notebook computers and any system requiring frequent wake and sleep cycles.
