Key Features
- Dual independent 1 A high-side switch channels with individual enable inputs for flexible selective load power control
- Integrated overcurrent limiting and thermal shutdown protection preventing damage to loads and board traces at fault conditions
- Input supply range of 2.7 V to 5.5 V covering both 3.3 V and 5 V USB and logic system rails
- Compact SOIC-8 package with tape-and-reel (T&R) option enabling automated SMT assembly in space-constrained power management designs
Applications
The MIC2506BMT&R is primarily used in USB power switching and port protection circuits, where it controls two independent 1 A load channels from a single 5 V or 3.3 V supply rail. It suits embedded systems, industrial controllers, and IoT hubs that require per-port over-current protection and soft-start enable sequencing for multiple downstream peripherals. Its compact SOIC-8 form factor makes it a practical choice for space-limited USB hub designs and multi-channel load switching on small form-factor PCBs.

Frequently Asked Questions
How many channels does MIC2506BMT&R provide, and what is the maximum current per channel for USB load switching?
The MIC2506BMT&R provides 2 independent high-side switch channels, each rated for a maximum continuous output current of 1 A. This makes each channel suitable for a single USB 2.0 port at full 500 mA load plus margin, or for general-purpose 1 A load switching on 5 V or 3.3 V rails. Both channels can operate simultaneously, giving a total combined switched current capacity of 2 A from the SOIC-8 package.
What built-in protection features does MIC2506BMT&R include to safeguard downstream USB peripherals from fault conditions?
The MIC2506BMT&R integrates thermal shutdown, current limiting, and reverse current blocking on each of its 2 channels. When an over-current condition is detected — such as a shorted USB peripheral — the switch limits current to protect board traces and automatically recovers once the fault clears. Thermal shutdown activates if junction temperature exceeds safe limits, and reverse current blocking prevents backfeed from the load into the supply rail, important for hot-plug and power-sequencing scenarios.
What supply voltage range does MIC2506BMT&R support, and is it compatible with both 3.3 V and 5 V system rails?
The MIC2506BMT&R operates from an input supply voltage range of 2.7 V to 5.5 V, making it directly compatible with both 3.3 V and 5 V system rails commonly found in USB host controllers, embedded SBCs, and industrial I/O boards. The 2.7 V lower limit also allows operation from slightly sagging 3.3 V supplies in battery-powered designs. Logic-level enable inputs are compatible with standard 3.3 V and 5 V microcontroller GPIO outputs.
How does MIC2506BMT&R compare to single-channel high-side switches for multi-port USB hub designs in terms of BOM efficiency?
Compared to using two separate single-channel high-side switches, the MIC2506BMT&R integrates 2 independent 1 A channels into a single SOIC-8 package, reducing component count, PCB footprint, and assembly cost for dual-port applications. A typical 4-port USB hub design can be built with just 2 MIC2506BMT&R devices instead of 4 discrete switches. This integration also simplifies layout by centralizing enable control logic while maintaining per-channel fault isolation with thermal shutdown and 1 A current limiting on each output.
