Power Distribution Switches, Load Drivers FAQ

How is the turn-on slew rate configured?

The slew rate is adjusted by connecting an external resistor (R2) and optionally a capacitor (C1) to the device pins, allowing control over inrush current during startup.

Does the device require an external level shifter?

No, the integrated NMOS control allows direct interfacing with logic signals as low as 1.0V, eliminating the need for external level shifters.
