Product Overview: AP2191AMPG-13

The AP2191AMPG-13 is a high-quality, single channel current-limited integrated high-side power switch, designed and manufactured by Diodes Incorporated. This advanced power switch is tailored for universal serial bus (USB) and other hot-swap applications. It is an essential component for modern electronic systems that require efficient power distribution and management.

This power switch is packaged in a small SOT-25 package, making it ideal for space-constrained applications. With its built-in fixed current limit, the AP2191AMPG-13 ensures protection against overcurrent conditions, which is crucial for safeguarding sensitive electronic components. Its fast response to fault conditions, combined with the automatic retry feature, enhances the reliability of the system it is integrated into.

Key Features

• Current Limiting: The device offers a precise current limiting function to protect the USB port and connected devices from excessive current draw that can lead to damage.
• Over-Temperature Protection: The AP2191AMPG-13 includes an over-temperature protection feature that shuts down the switch to prevent overheating, thereby ensuring the safety and longevity of the product.
• Reverse Current Blocking: This feature prevents current from flowing backward into the source when the switch is powered off, protecting the source from potential damage.
• Controlled Rise Time: The controlled rise time reduces inrush current, which is beneficial when managing capacitive loads and helps to minimize electrical noise in the system.
• Under-Voltage Lockout (UVLO): The UVLO function ensures that the switch remains off when the input voltage is below a certain threshold, thus protecting the device and the system.

Applications

The AP2191AMPG-13 is versatile and can be used in a variety of applications, including:

• USB peripherals and USB hub power management
• Hot-swap power management
• Portable electronic devices
• Battery-charger circuits
• Power distribution switches

With its robust protection features and compact design, the AP2191AMPG-13 from Diodes Incorporated is an excellent choice for designers looking to enhance the safety and efficiency of their USB and hot-swap applications.
