FPF2500

FPF2500 Description

The FPF2500 is an obsolete IC power switch from the IntelliMAX™ series, manufactured by onsemi. It is a general-purpose power distribution switch designed for surface mount applications. This device features a high-side output configuration with a maximum output current of 2A. The FPF2500 operates within a load voltage range of 4.5V to 20V and does not require a supply voltage (Vcc/Vdd). It is packaged in a SOT23-5 format and is available in tape and reel (TR) form. The device has a typical on-state resistance (Rds On) of 230mOhm and offers a single output. It includes fault protection features such as adjustable current limiting, over-temperature protection, and under-voltage lockout (UVLO). The FPF2500 is REACH unaffected and classified under ECCN EAR99. It has a moisture sensitivity level (MSL) of 1, indicating unlimited storage time under specified conditions. The switch is designed for on/off interface applications and is suitable for a variety of load driving tasks.

FPF2500 Features

The FPF2500 stands out with its unique combination of features that enhance its performance and reliability. Key features include:

• High-Side Output Configuration: This configuration allows for easy control and monitoring of the load, making it ideal for applications where the load needs to be isolated from the power supply.
• Auto Restart Feature: The auto restart feature ensures that the device can recover from fault conditions automatically, enhancing system reliability and reducing downtime.
• Adjustable Current Limiting: This feature allows for precise control over the maximum current that can flow through the switch, protecting both the switch and the load from overcurrent conditions.
• Over-Temperature Protection: The device includes over-temperature protection to prevent thermal runaway and ensure safe operation under various environmental conditions.
• Under-Voltage Lockout (UVLO): UVLO ensures that the switch remains off until the input voltage reaches a safe operating level, preventing erratic behavior at low input voltages.
• Low On-State Resistance (Rds On): With a typical Rds On of 230mOhm, the FPF2500 minimizes power loss and heat generation, making it efficient for power-sensitive applications.
• Moisture Sensitivity Level 1: The MSL 1 rating means the device can be stored indefinitely under specified conditions, reducing the risk of moisture-related failures.
