AP2511AMP-13 USB Power Switch from Diodes Incorporated

The AP2511AMP-13 is a high-quality, integrated current-limited USB power switch designed 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 component is engineered to provide a single USB port power switch with a built-in current limit feature, making it an ideal choice for a wide range of applications including USB host devices, desktop computers, notebooks, monitors, and many other consumer electronic devices.

This power switch is specifically designed to protect USB ports by limiting the output current when an excessive load is placed on the output, such as a short circuit. The AP2511AMP-13 operates from a 2.7V to 5.5V input voltage range, making it versatile for various USB power applications. The device is capable of delivering up to 2.1A of continuous current, ensuring compatibility with high-power USB peripherals.

The AP2511AMP-13 incorporates multiple safety features, including over-current protection, thermal shutdown, and under-voltage lockout, which provide enhanced protection for both the USB port and the connected devices. The over-current protection mechanism is designed to be automatically triggered, reducing the output current to a safe level when an over-current event is detected. Additionally, the thermal shutdown feature protects the device from overheating, while the under-voltage lockout ensures stable operation by disabling the output when the input voltage falls below a certain threshold.

This USB power switch comes in a space-saving MSOP-8 package, which is ideal for space-constrained applications. The AP2511AMP-13 is also characterized by its low on-resistance, high bandwidth, and fast short-circuit response time, which contribute to its efficient and reliable performance. The device is compliant with USB 2.0 and USB 3.0 power distribution standards, ensuring interoperability with existing and future USB devices.

Overall, the AP2511AMP-13 from Diodes Incorporated represents a robust solution for USB power delivery and protection, offering design flexibility and reliability for a multitude of USB-enabled electronic devices.
