Product Overview: AP2141DSG-13

The AP2141DSG-13 is a high-performance, single-channel current-limited integrated high-side power switch designed by Diodes Incorporated for USB and other hot-swap applications. This power switch is optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Key Features

• Current Limiting: This device provides a precise current limiting function, which protects the USB port by preventing excessive current from flowing in the event of a load short circuit.
• Fast Response Time: The AP2141DSG-13 responds quickly to fault conditions, with a typical response time of less than 2ms, ensuring reliable protection for sensitive components.
• Thermal Shutdown Protection: It includes thermal shutdown protection that automatically shuts off the power switch in the event of overheating, which is critical for maintaining the integrity and longevity of electronic components.
• Controlled Rise Time: The controlled rise time reduces the current surge during turn-on, which minimizes electromagnetic interference (EMI) and potential damage to other components.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates at the correct voltage level, preventing malfunctions due to undervoltage conditions.

Applications

The AP2141DSG-13 is versatile and can be used in various applications, including:

• USB peripherals and USB hubs
• Hot-swap power management
• Battery charger circuits
• Portable electronic devices
• Overcurrent and short-circuit protection circuits

Product Specifications

The AP2141DSG-13 is offered in a small surface-mount package, the SOT-25, making it suitable for compact designs. It operates over a voltage range of 2.7V to 5.5V, which is compatible with standard USB power specifications. The switch's maximum continuous output current is 1.2A, which is sufficient for most USB-powered devices. Additionally, the device's low quiescent current and low shutdown current make it an energy-efficient solution for power management designs.

With its robust feature set and Diodes Incorporated's commitment to quality, the AP2141DSG-13 is an excellent choice for designers looking for a reliable high-side power switch to enhance their USB applications' safety and performance.
