Operating from a 2.5V to 5.5V power supply, the SLG59M1714V is a 15mΩ, 4A single-channel load switch with back⁠-to-⁠back reverse‑current blocking when the power switch is disabled. With a fixed VOUT slew rate of 2.8V/ms, inrush current is internally limited. Incorporating two-stage current protection as well as thermal protection and fault signaling, the SLG59M1714V is designed for all 0.8V to 5.5V power rail applications. Fully specified over the -40 °C to 85 °C temperature range, the SLG59M1714V is packaged in a space-efficient, low thermal resistance 1.6mm x 2.5mm STQFN package.
