The AP2151DSG-13 is a high-quality, single-channel USB power switch from Diodes Incorporated, designed to provide over-current and thermal protection for systems that require power distribution switches. This product is particularly suitable for applications such as USB peripherals, portable electronics, and other power-sensitive devices that require precise control over their power supply.

Key Features

• Single Channel Current-Limiting: The device offers a single channel of current-limiting, ensuring that the connected device does not draw more power than it is designed to handle, which can prevent damage from overcurrent situations.
• Fast Response Time: With a fast response time to fault conditions, the AP2151DSG-13 quickly reacts to over-current and thermal events, offering a high level of protection for sensitive components.
• Low On-Resistance: The low on-resistance of the built-in MOSFET switch ensures minimal voltage drop and power loss, providing efficient power distribution to the load.
• Thermal Shutdown Protection: The thermal shutdown feature protects the device and the system from damage due to excessive heat, enhancing the overall reliability of the application.
• Controlled Rise Time: The AP2151DSG-13 is designed with a controlled rise time to reduce inrush current, which can be particularly beneficial for preventing glitches on the power line during device connection.

Applications

Due to its robust protection features and efficient power management, the AP2151DSG-13 is ideal for a wide range of applications, including:

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