AP2552FDC-7

Power Distribution Switches, Load Drivers Overview

The AP2552FDC-7 is a single-channel precision adjustable current-limited power switch from Diodes Incorporated, designed for USB power distribution. It operates within a supply voltage range of 2.7 V to 5.5 V and supports up to 2.1 A of continuous load current. The device features an on-resistance of 105 mOhms maximum and includes programmable current limiting via an external resistor. Key protection mechanisms include over-temperature shutdown, under-voltage lockout, and reverse current blocking. It is housed in a U-DFN2020-6 package with a maximum operating temperature of 85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Precision adjustable current limiting capability for precise load management
• Integrated thermal shutdown and under-voltage lockout protection
• Reverse current blocking functionality to prevent backflow

Power Distribution Switches, Load Drivers Applications

• USB port power switching and distribution
• Battery-powered equipment load protection
• High-side power switch applications requiring current regulation

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'FDC' against the manufacturer's official datasheet to confirm the exact package type (U-DFN2020-6) and tape/reel specifications. Ensure that the required current limit setting aligns with the external resistor values documented in the electrical characteristics table. Cross-reference the RoHS status and lead-free compliance details directly with the component marking to avoid substitution errors.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single high-side switch with adjustable current limits is required for 5V bus architectures. It is suitable for designs needing integrated thermal protection and reverse current blocking without external diodes. Consider the U-DFN2020-6 footprint constraints and the need for an external sense resistor to set the trip current threshold during the schematic phase.
