General Description

The SLG59H1020V is a high-performance, self-powered

50 mΩ NMOS load switch with back-to-back reverse-current

blocking designed for all 4.5 V to 20 V power rails up to 3 A.

Using a proprietary MOSFET design, the SLG59H1020V

achieves a stable 50 mΩ RDSON across a wide input voltage

range. In combining novel FET design and copper pillar

interconnects, the SLG59H1020V package also exhibits a low

thermal resistance for high-current operation.

Designed to operate over a -40°C to 85°C range, the

SLG59H1020V is available in a low thermal resistance,

RoHS-compliant, 1.6 x 3.0 mm STQFN package.
