• Integrates USB On-The-Go (OTG) host capability for peripheral power supply
• Includes power path management for system load prioritization
• Supports production test modes via programmable interfaces

Battery Chargers Applications

• Smartphones requiring integrated USB host charging
• Portable media players with OTG connectivity
• Mobile communication devices using Li-Ion/Polymer batteries

Battery Chargers Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor was acquired by onsemi. Ensure the specific suffix matches the required packaging format. Confirm RoHS compliance status through official datasheets or component markings before integration into designs.

Battery Chargers Selection Notes

Select this component when USB OTG host functionality is required alongside battery charging in space-constrained mobile applications. The small WLCSP footprint suits dense PCB layouts. Verify that the 1.55A charge current meets the target battery specifications and thermal constraints.

Battery Chargers Part Context

This part belongs to the FAN5400 series of battery management ICs designed for portable electronics. It combines charging control with USB OTG host features, distinguishing it from standard chargers. The series targets smartphones and tablets needing compact power management solutions.

Battery Chargers Replacement Considerations

Check for direct equivalents within the FAN5400 family, such as the FAN5400UCX or FAN54041UCX, ensuring pin compatibility and functional overlap. Verify if updated onsemi designations apply due to corporate acquisition.
