Silego Technology’s Power Division introduced the Nanopower load switch family with two products: the SLG59M1470V, supporting up to 6A loads, and the SLG59M1460V supporting up to 2A loads. Silego’s proprietary sub-micron copper power FET technology is presented as the smallest full-featured, high efficiency power switches down to 1 x 1 mm in standard plastic packaging.

“Mobile system designers desire load switches that achieve three parameters at the same time: fast turn on, low Rds(ON), and low power consumption. Existing P-Channel MOSFET solutions achieve decent turn on speed with low power consumption, but suffer high Rds(ON) when the power rail is below 2.5 V”

Nanopower load switches support very fast power rail switching down to 9.5 μs. 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 35 nA in active mode. The ultra-low power consumption during sleep mode and low Rds(ON) performance during active mode significantly increases battery life.

“Mobile system designers desire load switches that achieve three parameters at the same time: fast turn on, low Rds(ON), and low power consumption. Existing P-Channel MOSFET solutions achieve decent turn on speed with low power consumption, but suffer high Rds(ON) when the power rail is below 2.5 V,” said Jay Li, Director of Marketing. “Our Nanopower devices are the world’s first integrated load switches that achieve all three key mobile performance parameters. This device is widely adopted on many next generation mobile devices including tablets, notebooks, and smartphones.”

SLG59M1470V is packaged in a 9 pin, 1.5 x 2.0 mm STDFN package. The device can switch power rails down to 1.0 V. The Rds(ON) of the SLG59M1470V is rated at 7.4 mΩ.

SLG59M1460V is packaged in an 8 pin, 1.0 x 1.6 mm STDFN package. The device can switch power rails down to 1.0 V. The Rds(ON) of the SLG59M1460V is rated at 21.3 mΩ.
