FPF2312MPX

Power Distribution Switches, Load Drivers Overview

The FPF2312MPX is a dual-output power distribution switch manufactured by Fairchild Semiconductor. It features a P-Channel output configuration designed for high-side switching applications. The device supports a load voltage range of 1.8V to 5.5V and utilizes an On/Off interface for control. It does not require a separate supply voltage (Vcc/Vdd). The component is housed in an 8-MLP package with dimensions of 3mm x 3mm, containing eight terminals.

• Direct On/Off interface logic compatibility

Power Distribution Switches, Load Drivers Applications

• Portable electronic device power management
• Peripheral power distribution circuits
• Battery-powered system load switching

Power Distribution Switches, Load Drivers Procurement Notes

Verify the manufacturer source carefully, as Fairchild Semiconductor's semiconductor division was acquired by ON Semiconductor. Ensure the specific part number matches the original Fairchild datasheet specifications if legacy compliance is required. Confirm package marking codes and date codes against official documentation to distinguish between original Fairchild production and subsequent ON Semiconductor manufacturing runs.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a dual-channel high-side switch is required for low-voltage loads between 1.8V and 5.5V. The absence of a required Vcc pin simplifies board layout compared to switches needing auxiliary supplies. Ensure the application current does not exceed the typical 600mA rating specified for this series variant. Consider the MLP package size for space-constrained designs.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the AccuPower family of load switches, which are designed for efficient power distribution in portable electronics. The FPF23xx series typically integrates protection features such as over-current limiting. The MPX suffix indicates the specific tape-and-reel packaging format used for automated surface-mount assembly processes.

Power Distribution Switches, Load Drivers Replacement Considerations

The FPF2310MPX is a documented single-channel variant within the same product family. Cross-reference electrical parameters carefully, as channel count differences affect board footprint and routing requirements. Verify that the replacement maintains the required P-Channel high-side configuration and voltage range compatibility.
