Silego Technology Introduces a 28 mΩ, Ultra-Low Quiescent Current P-Channel GreenFET3™ Load Switch

SANTA CLARA, Calif. — (BUSINESS WIRE) — March 24, 2014 — Silego Technology introduces the SLG59M1557, a 28 mΩ P-Channel, ultra-low quiescent current GreenFET3 load switch. The product is based on Silego’s proprietary sub-micron CuFET technology. The device can achieve 0.1uA typical and 1uA maximum quiescent current in both ON and OFF states. This device has an integrated level shift function for the ON pin, which allows the system MCU to directly turn on or off the load switch without any discrete logic or level shifting components.

“The low quiescent current performance and integrated level shift are ideal features for applications such as wearable electronics and ultra-low power portable electronics. These devices can achieve world class power reduction and board space savings,” said Director of Marketing, Jay Li “and comparing to existing products on the market that only operate up to 3.6 V, the SLG59M1557V’s wide voltage range (1.5 V to 5.5 V) covers the entire single cell lithium-ion battery voltage range”.

The first version of this product is introduced in the STDFN package (1.0x1.0x0.55 mm). The STDFN package offers superb mechanical protection. The package can be directly soldered on the PCB or flexible cable without using any PCB under-fill. The STDFN package has a significantly higher mechanical stress tolerance than a WLCSP packaging, both during manufacturing and end use. This is particularly valuable for wearable electronics which may be frequently dropped by users.

The 59M1557 is also available in Silego’s proprietary Lo-ZTM ETDFN package technology, which can reduce the STDFN package max height from 0.50 mm down to 0.3 mm. Please contact Silego for more information.
