Features and Benefits

• Integrated 70mΩ N-channel MOSFET switch for efficient power distribution.

• Current limit set at 1A to prevent damage from overcurrent conditions.

• Thermal shutdown protection to prevent overheating.

• Under-voltage lockout (UVLO) ensures the switch remains off when the input voltage is too low.

• Controlled rise time to reduce inrush current impact.

• Small SOT-23 package suitable for space-constrained applications.

Applications

• USB hubs, docks, and peripherals requiring individual power control.

• Hot-swap power supplies for servers and network interfaces.

• Portable consumer electronics where power conservation is critical.

Advantages

• Enhanced system safety through built-in current limit and thermal protection.

• Improved system reliability with UVLO feature.

• Optimized for USB power management with controlled rise time.

• Space-saving design with minimal external components required.

Implementation Examples

• Power control for individual USB ports on a multi-port USB hub.

• Overcurrent and thermal protection in battery-powered accessories.
