    FPF1320UCX Typical application Circuitry


    The FPF1320UCX is a dual-input, single-output power switch designed for USB and battery-powered devices. This chip allows seamless transition between two power sources, ensuring continuous power supply to the load.It is frequently utilized in applications where power source switching is crucial, such as those found in smartphones, tablets, and portable electronic gadgets.


    The FPF1320UCX features two input power channels (IN1 and IN2) and one output channel (OUT). It integrates a bidirectional load switch that can control the direction of current flow based on the priority of the power sources. The chip also includes under-voltage lockout (UVLO) and over-current protection (OCP) to safeguard the device and the load.


    - Smartphones and Tablets: For switching between battery and USB power.

    - Portable Electronics: In devices like portable speakers, where seamless power source transition is required.

    - Wearable Devices: To manage power in smartwatches and fitness trackers.


    - Voltage Range: Typically operates between 1.5V to 5.5V.

    - Current Rating: Can handle up to 2A of continuous current.

    - Switching Time: Fast transition between power sources, typically in the order of microseconds.

    Circuit Design for a Smartphone Application:

    1. Power Source Inputs: Connect the battery to IN1 and the USB power to IN2. This sets the battery as the primary power source.

    2. Output Connection: Connect OUT to the load, which in this case is the smartphone's power management IC.

    3. Control Logic: Use a microcontroller or a control circuit to manage the SEL pin. The SEL pin determines the priority of the power sources. For example, when the SEL pin is low, IN1 is active; when high, IN2 is active.

    4. Protection Features: Ensure that the UVLO threshold is correctly set to prevent deep discharge of the battery. Additionally, configure the OCP to protect against overcurrent situations.

    Considerations for Circuit Design:

    - Power Source Compatibility: Ensure that the power sources connected to IN1 and IN2 are compatible with the voltage and current specifications of the FPF1320UCX.

    - Thermal Management: Since the chip can handle up to 2A, proper heat dissipation measures should be in place to prevent overheating.

    - Load Requirements: Consider the power requirements of the load and ensure that the FPF1320UCX can provide sufficient current without triggering overcurrent protection.

    In conclusion, the FPF1320UCX offers a versatile solution for managing power in portable devices, ensuring seamless transition between power sources while providing essential protection features.
