Product Overview: AP2172ASG-13 from Diodes Incorporated

The AP2172ASG-13 is a high-quality power distribution switch from Diodes Incorporated, designed for USB and other hot-swap applications. It is a single-channel, current-limited, integrated high-side power switch optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Key Features

• Current Limiting: This device offers precise current limiting to protect the USB port and downstream devices from damage due to overcurrent conditions. The current limit threshold is factory-programmed, which provides consistent performance.
• Fast Transient Response: The AP2172ASG-13 is engineered to react quickly to transient loads, thereby ensuring stable operation of connected devices during sudden changes in demand.
• Reverse Current Blocking: A built-in feature prevents any reverse current flow from the output to the input when the switch is powered off, thus safeguarding the upstream devices from potential damage.
• Thermal Shutdown Protection: The device includes an over-temperature protection circuit that shuts down the power switch to prevent excessive heat from damaging the IC and potentially the external components.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the power switch remains off when the input voltage falls below a specific threshold, thus protecting the circuitry during low voltage conditions.

Applications

The AP2172ASG-13 is ideal for a variety of applications where power distribution and protection are critical. These include:

• USB hubs, peripherals, and monitors
• Hot-swap power supplies
• Battery-charger circuits
• Portable consumer electronics

Package and Availability

The AP2172ASG-13 comes in a space-saving SOP-8 package, providing a compact solution for space-constrained applications. It is available in tape and reel form for automated assembly processes, ensuring ease of integration into existing production lines.

With its robust feature set and reliable performance, the AP2172ASG-13 from Diodes Incorporated is an excellent choice for designers looking to enhance the safety and efficiency of their power distribution systems.
