Product Overview: AP2161DWG-7

The AP2161DWG-7 is a high-quality, integrated circuit designed and manufactured by Diodes Incorporated, a leading global manufacturer and supplier of high-performance semiconductor products. This particular device is a current-limited power switch designed for USB applications, providing protection for both the USB port and the load connected to it.

Key Features

• Current Limiting: The AP2161DWG-7 features a precise current-limiting function that helps to prevent damage to USB ports by controlling the amount of current that can flow through the switch. This is particularly important for protecting sensitive electronic devices from potential over-current conditions.
• Over-Temperature Protection: The device includes an over-temperature protection feature that automatically shuts off the power switch in the event of excessive heat, thereby safeguarding the circuit and connected devices from thermal damage.
• Fast Response Time: With a quick response time to fault conditions, the AP2161DWG-7 ensures that your devices are protected promptly, reducing the risk of damage.
• Low Power Consumption: Designed with power efficiency in mind, the AP2161DWG-7 has a low quiescent current, which minimizes power consumption when in operation, making it suitable for battery-powered applications.

Applications

The AP2161DWG-7 is versatile and can be used in a wide range of applications, particularly those involving USB power distribution. Some common uses include:

• USB hubs
• USB peripheral devices
• Hot-swap USB supplies
• Over-current protection for set-top boxes, TVs, and other consumer electronics

Product Specifications

The AP2161DWG-7 comes in a small SOT-25 package, making it an excellent choice for space-constrained applications. It operates over a voltage range of 2.7V to 5.5V, which covers standard USB power supply levels. The switch current limit is typically set at 0.5A, which aligns with the standard USB current specifications for peripherals.

In summary, the AP2161DWG-7 from Diodes Incorporated is a robust and reliable solution for managing power delivery and protection in USB-powered devices. Its combination of current limiting, over-temperature protection, low power consumption, and fast response time makes it an essential component for any USB power management system.
