18.3 mOhm load switch for 0.75 V–3.6 V rails
The typical on-resistance of 18.3 mOhm keeps conduction losses low — at 2 A the voltage drop is roughly 37 mV, which matters for tight core rails like 1.2 V or 1.8 V. The switch integrates a slew-rate-controlled turn-on to limit inrush current and a load-discharge feature that pulls the output to ground when disabled — no floating output on shutdown. The control input is non-inverting and active-high, with no separate Vcc supply required.
BOM-fit: Rds(on), current, and package
The 18.3 mOhm typical Rds(on) is specified at the operating point — it sets the voltage drop and self-heating. The 0.75 V minimum load voltage lets it switch sub-1 V rails common in modern SoCs and FPGAs. The 1:1 input-to-output ratio means it is a simple pass-gate — no level shifting or sequencing logic. The On/Off interface is a single GPIO-compatible pin. No external Vcc bias rail is needed; the switch is self-powered from the load voltage.
