SLG59H1019V
A 13 mΩ, 5 A, Load Switch with Soft-start,
Protection Features, and MOSFET Current Monitor Output
General Description
Pin Configuration
RSET IOUT
The SLG59H1019V is a high-performance 13 mΩ NMOS load
switch designed to control 4.5 V to 25.2 V power rails up to 5
A. Using a proprietary MOSFET design, the SLG59H1019V
achieves a stable 13 mΩ RDSON across a wide input voltage
range. In combining novel FET design and copper pillar
interconnects, the SLG59H1019V package also exhibits a low
thermal resistance for high-current operation.
