Applications
MIC2005-0.5YM6 TR is designed for USB port power switching in laptops, desktops, and embedded systems, protecting downstream USB devices from over-current faults up to 500 mA. It is also used in industrial controllers, set-top boxes, and USB hubs where reliable power sequencing and fault detection are required. The compact 6-pin SOT-23 footprint makes it ideal for space-constrained USB Type-A or Type-B port designs.

Frequently Asked Questions
How does MIC2005-0.5YM6 TR protect a USB port from over-current conditions?
MIC2005-0.5YM6 TR limits output current to 500 mA and triggers an open-drain fault flag when current exceeds this threshold. It then automatically retries after a timeout cycle, protecting both the host system and downstream USB devices from sustained short-circuit or overload conditions.
What is the input voltage range for MIC2005-0.5YM6 TR?
MIC2005-0.5YM6 TR operates from a 2.5 V to 5.5 V input supply, making it compatible with standard 5 V USB bus power as well as lower-voltage 3.3 V bus architectures found in modern embedded and portable systems.
Can MIC2005-0.5YM6 TR be used in a USB hub to switch multiple ports independently?
Yes, each MIC2005-0.5YM6 TR controls one high-side switch channel rated at 500 mA. For a 4-port USB hub, four devices can be used with independent active-low enable pins connected to a microcontroller GPIO, allowing per-port power management and fault isolation.
How small is the MIC2005-0.5YM6 TR package and what does it mean for PCB layout?
MIC2005-0.5YM6 TR comes in a 6-pin SOT-23 package measuring approximately 2.9 mm × 1.6 mm, requiring minimal PCB footprint and enabling placement adjacent to the USB connector with short trace runs that reduce resistive losses at 500 mA load currents.
