With a 2.7V to 5.5V input voltage range, it is versatile and well-suited for a wide array of USB peripherals and other portable devices.

Key Features

• Current Limiting: The AP2141FMG-7 provides precise current limiting to protect the host device and the USB port from over-current conditions. This feature ensures safe operation even under fault conditions, such as when a downstream device draws excessive current.
• Fast Response Time: With a fast response time to fault conditions, this power switch quickly disables the output, preventing damage to connected devices.
• Reverse Current Blocking: This function prevents current from flowing backward from the output to the input when the switch is turned off, safeguarding the input source from potential harm.
• Thermal Shutdown Protection: The AP2141FMG-7 includes thermal shutdown protection that disables the output to prevent overheating, thereby ensuring the longevity and reliability of the device and the system.
• Controlled Rise Time: The device features a controlled output rise time to minimize current surges during turn-on, which is particularly important in sensitive applications.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates within the safe voltage range, protecting it and the connected peripherals from low-voltage conditions.

Applications

The AP2141FMG-7 is an excellent choice for a range of applications, including:

• USB hubs, peripherals, and portable devices
• Battery-charging circuits and power distribution
• Hot-swap supplies

With its comprehensive protection features and compact form factor, the AP2141FMG-7 from Diodes Incorporated is a robust solution for power management and distribution in USB and portable applications, ensuring safe and efficient operation across various conditions and requirements.
