Detailed Pin Configuration

The FPF1108 features a SOT23-6 package with the following pin configuration:

____ EN | | GND IN | | OUT FB |____| VIN

Pin Description: - EN: Enable pin, used to control the ON/OFF state of the power switch. - IN: Input pin, connected to the power source. - OUT: Output pin, connected to the load. - FB: Feedback pin, used for overcurrent protection and thermal shutdown.

Functional Features

  1. Overcurrent Protection: The FPF1108 incorporates overcurrent protection, which helps prevent damage to the load and the IC itself in case of excessive current flow.
  2. Thermal Shutdown Protection: In situations where the temperature exceeds the specified limit, the FPF1108 activates thermal shutdown protection, ensuring safe operation.
  3. Under Voltage Lockout (UVLO): The UVLO feature ensures that the power switch remains off when the input voltage falls below a certain threshold, preventing improper operation.
  4. Fast Turn-On and Turn-Off Times: The FPF1108 offers fast turn-on and turn-off times, enabling efficient power management and control.

Advantages and Disadvantages

Advantages: - Compact SOT23-6 package for space-constrained applications. - Integrated protection features enhance system reliability. - Low RDS(ON) MOSFET minimizes power loss and improves efficiency. - Wide input voltage range allows compatibility with various power sources.

Disadvantages: - Maximum continuous current limited to 1.8A, which may not be sufficient for high-power applications. - Limited operating temperature range (-40°C to +85°C) restricts usage in extreme environments.

Working Principles

The FPF1108 operates as a power switch by controlling the flow of current between the input and output pins. When the enable pin (EN) is high, the power switch turns on, allowing current to flow from the input (VIN) to the output (OUT). Conversely, when the EN pin is low, the power switch turns off, interrupting the current path.

The integrated protection features, such as overcurrent protection and thermal shutdown, ensure safe operation by monitoring the current and temperature conditions. In case of an overcurrent event or excessive temperature, the FPF1108 activates the corresponding protection mechanism to safeguard the load and the IC.
