The MIC2075-2BMM from Microchip Technology is a robust single-channel integrated power distribution switch designed for USB and other hot-swap applications. This compact and efficient device comes in an 8-pin MSOP (Micro Small Outline Package) that is well-suited for space-constrained applications.
Key Features
- Current Limiting: The MIC2075-2BMM offers programmable current limiting to protect the host device from overcurrent conditions. This ensures safe operation and extends the life of both the switch and the connected peripherals.
- Thermal Shutdown: With built-in thermal shutdown protection, the device automatically turns off if it exceeds a certain temperature threshold, preventing thermal damage.
- Under-Voltage Lockout (UVLO): The UVLO feature ensures that the switch remains off if the input voltage falls below a specified level, safeguarding the circuitry during low voltage conditions.
- Fast Short-Circuit Response: The device is capable of responding quickly to short-circuit conditions, minimizing the risk of damage to the switch and the power source.
- Controlled Rise Time: The MIC2075-2BMM has a controlled output rise time which reduces inrush current, thereby mitigating the potential for system voltage droop when heavy loads are applied.
Applications
The MIC2075-2BMM is versatile and can be used in a variety of applications including:
- USB hubs, peripherals, and powered ports
- Hot-swap power management
- Portable consumer electronics
- Industrial and medical equipment
Technical Specifications
With an input voltage range of 2.7V to 5.5V, the MIC2075-2BMM is ideal for low voltage applications. It supports a continuous output current of up to 0.5A, making it suitable for a wide range of peripheral devices. The switch's low quiescent current and low shutdown current contribute to its energy-efficient design.
Conclusion
The MIC2075-2BMM from Microchip Technology is an excellent choice for designers looking for a reliable and high-performance power distribution switch. Its comprehensive protection features and small form factor make it an essential component for any power management solution.
