MIC2549A-1BTS from Microchip Technology

The MIC2549A-1BTS is a high-quality integrated circuit from Microchip Technology, designed to provide reliable and efficient power management solutions. This product is a single-channel power distribution switch optimized for general-purpose power distribution requiring circuit protection. The device is particularly suitable for applications such as USB and other hot-swap applications.

Key Features:

• Integrated Single Channel: The MIC2549A-1BTS offers a single channel for power distribution, simplifying design and reducing component count.
• Adjustable Current Limit: Designers can set the current limit to meet the needs of their specific application, providing flexibility and protection against overcurrent conditions.
• Thermal Shutdown: With built-in thermal shutdown, the device protects itself and the downstream components from damage due to excessive heat.
• Under-voltage Lockout (UVLO): This feature ensures that the switch remains off if the input voltage is too low, preventing malfunction and potential damage.
• Fast Short-Circuit Response: The MIC2549A-1BTS reacts quickly to short-circuit conditions, minimizing the risk to connected components.
• Status Flag: An output flag is provided to indicate fault conditions, allowing for system-level monitoring and response.
• Soft-Start: The soft-start feature limits inrush current during turn-on, which is particularly useful for applications with capacitive loads.
• 5.5V to 13.2V Operating Range: The device operates over a wide voltage range, making it versatile for various applications.
• Active-High Enable: An active-high enable input allows for simple on/off control of the power switch.

Applications:

• USB Hubs, Peripherals, and Powered Ports
• Hot-Swap Power Supplies
• Portable Devices
• Notebook Computers
• Peripheral Power Management

The MIC2549A-1BTS is available in a small, space-saving 8-pin TSOT-23 package, making it ideal for compact designs.
