SLG59H1005V
A 22 V, 50 mΩ, 3 A, Reverse Blocking Load Switch
with V Lockout Select and MOSFET Current Monitor Output

General Description
Pin Configuration
The SLG59H1005V 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 22 V power rails up to 3 A.
Using a proprietary MOSFET design, the SLG59H1005V
achieves a stable 50 mΩ RDSON across a wide input voltage
range. In combining novel FET design and copper pillar
interconnects, the SLG59H1005V package also exhibits a low
thermal resistance for high-current operation.
