The AP2280-2WG-7 is a high-performance, single-channel, current-limited integrated high-side power switch from Diodes Incorporated, crafted for USB and other hot-swap applications. This compact, efficient device is an essential component for modern electronic systems that require power distribution controls with protective features.

Key Features

• Current Limiting: The AP2280-2WG-7 offers precise current limiting to protect the host device from over-current conditions, which can be particularly useful in preventing damage to USB ports and connected devices.
• Fast Transient Response: With its quick response to load changes, this power switch ensures stable operation, minimizing the risk of voltage drops that could cause system resets or other malfunctions.
• Reverse Current Blocking: This feature prevents current from flowing backward through the switch when it is powered off, which is critical for protecting the circuitry from potential damage.
• Thermal Shutdown Protection: The built-in thermal shutdown mechanism safeguards the device against overheating, which enhances the longevity and reliability of the product.
• Controlled Rise Time: The AP2280-2WG-7 is designed to mitigate inrush current during power-up, thereby reducing the stress on the system and extending the life of the electronic components.
• Under-Voltage Lockout (UVLO): This safety feature ensures that the power switch operates only when the input voltage is within an acceptable range, preventing malfunctions caused by low voltage conditions.
