The FPF2124 is a Current Limiting Power Switch intended for applications where precision current limiting is required to protect source supplies and connected loads. This device offers a comprehensive set of protection features and is well-suited for USB power distribution and hot-swap applications.

Applications

• USB Power Distribution
• Hot-Swap Applications
• General Purpose Power Switching with Current Limit
• Power Management in Portable Devices

Features

• Precise Adjustable Current Limit
• Overcurrent Protection
• Short-Circuit Protection
• Thermal Shutdown
• Reverse Voltage Protection
• Fault Reporting

Benefits

• Protects power sources and loads from damage due to overcurrent or short-circuit conditions.
• Allows for safe hot-swapping of devices without disrupting system operation.
• Provides precise control over the maximum current delivered to the load.
• Enhances system reliability and prevents component failures.

Additional Details

The FPF2124 features a highly accurate current limit that can be adjusted using an external resistor. The device also includes built-in protection against overcurrent, short-circuit, and thermal overload conditions. Reverse voltage protection prevents current from flowing backward into the power source. A fault reporting output indicates when a protection event has occurred. The FPF2124 is available in a space-saving SOT23-5 package.
