The AP2161WG-7 is a high-quality, integrated circuit designed and manufactured by Diodes Incorporated, a leading global manufacturer and supplier of high-quality application-specific standard products within the broad discrete, logic, analog, and mixed-signal semiconductor markets. This particular product is a current-limited, single-channel USB power switch optimized for USB and other hot-swap applications.

Key Features

• Current Limiting: The AP2161WG-7 provides a precise current limiting function, which is crucial for preventing damage to USB ports by controlling the amount of power that can flow through the switch.
• Over-Temperature Protection: It includes an over-temperature protection feature that automatically shuts down the power switch to prevent overheating, ensuring the longevity and reliability of both the switch and the connected device.
• Fast Transient Response: The device is designed with a fast transient response, which is essential for maintaining stable operation during sudden changes in load.
• Reverse Current Blocking: This feature prevents current from flowing backward through the switch when it is powered off, protecting the upstream devices from potential damage.

Applications

The AP2161WG-7 is ideal for a variety of applications where USB power control and protection are necessary. It is commonly used in:

• USB hubs, peripherals, and monitors
• Battery chargers and docking stations
• Portable devices with USB interfaces

Product Specifications

The AP2161WG-7 operates over a voltage range of 2.7V to 5.5V, making it suitable for low-voltage and standard USB power operations. It is available in a small 6-pin SOT-25 package, which is ideal for space-constrained applications. The switch also features a low quiescent current and a built-in soft-start to minimize inrush current during plug-in events.
