Product Overview: AP2161DM8G-13 from Diodes Incorporated

The AP2161DM8G-13 is a high-performance, single-channel current-limited integrated high-side power switch from Diodes Incorporated, designed for USB and other hot-swap applications. This power switch is optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Encased in a small SOP-8 (MSOP-8) package, the AP2161DM8G-13 offers a compact solution for over-current protection and complies with USB standards. Its precision current limiting ensures protection by controlling the output current to a safe level by switching off when a load exceeds the current limit threshold.

Key Features:

• Current Limiting: The device provides 0.9A (min) to 1.2A (max) programmable current limiting, which is suitable for a wide range of applications.
• Fast Response Time: With built-in fast response to fault conditions, the AP2161DM8G-13 responds to over-current events quickly, minimizing the risk to the circuit components.
• Thermal Shutdown Protection: It includes thermal shutdown protection that automatically shuts down the output to prevent overheating, enhancing the overall safety and longevity of the device.
• Reverse Current Blocking: This feature prevents current from flowing backward from the output to the input, thus protecting the source from potential damage.
• Under-Voltage Lockout (UVLO): The UVLO function ensures that the device operates correctly only when the input voltage is within the specified range.
• Soft-Start Mechanism: The soft-start capability limits inrush current during plug-in events, reducing stress on the power source and extending the system's operational life.

Applications:

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

The AP2161DM8G-13 is RoHS compliant and lead-free, making it a responsible choice for developers looking to create environmentally friendly electronic products. With its comprehensive protection features and compact design, the AP2161DM8G-13 is an ideal choice for a wide range of applications requiring power switch functionality with a high level of reliability and efficiency.
