Product Overview: AP2181FMG-7

The AP2181FMG-7 is a high-quality, single-channel current-limited integrated high-side power switch from Diodes Incorporated, designed for USB and other hot-swap applications. This advanced power switch is optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Key Features

• Current Limiting: The device provides precise current limiting to protect the host device from overcurrent conditions. It is capable of delivering a continuous output current of up to 1.5A, making it suitable for a wide range of peripherals and USB devices.
• Fast Response Time: It features a fast response time to fault conditions, ensuring quick protection for sensitive components. The built-in output discharge function allows for rapid discharge of the load capacitance on shutdown.
• Reverse Blocking: When powered off, the AP2181FMG-7 prevents any backflow current from the output to the input, safeguarding the upstream devices from potential damage.
• Thermal Shutdown Protection: The device incorporates thermal shutdown protection that disables the power switch in the event of excessive power dissipation, preventing thermal runaway.
• Controlled Rise Time: The controlled rise time reduces the current spikes and electromagnetic interference (EMI) that can occur during the power switch operation, enhancing system reliability.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the power switch remains off when the input voltage is below a certain threshold, thus protecting the device and the system.

Applications

The AP2181FMG-7 is suitable for a variety of applications that require power distribution and protection. Its primary applications include:

• USB peripherals and equipment
• Hot-swap power management
• Portable consumer devices
• Power distribution switches

Package and Availability

The device is available in a space-saving 6-pin DFN2020 package, which is RoHS compliant and Halogen-free.
