MIC2537Quad USB High-Side 100mA Current Limiting Power Switch | PMIC | 8 | Active | The MIC2537 is a cost-effective high-side power switch with four independently controlled channels, optimized for buspowered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements.
The MIC2537 satisfies the following USB requirements: each switch channel supplies up to 100mA as required by USB bus-powered downstream devices; fault current is limited to typically 250mA, well below the UL 25VA safety requirements; and a flag output is available to indicate fault conditions to the local USB controller. Soft start eliminates the momentary voltage drop on the upstream port that may occur when the switch is enabled in bus-powered applications.
Additional features include thermal shutdown to prevent catastrophic switch failure from high-current loads and 3.3V and 5V logic compatible enable inputs.
The MIC2537 is available in active-high and active-low versions in a 16-lead SOP package. |

MIC2544AAdjustable 1.5A Single High-Side Current Limit Power Switch | Power Distribution Switches, Load Drivers | 17 | Active | The MIC2544 and MIC2548 are integrated, high-side power switches optimized for low loss DC power switching and other power management applications, including Advanced Configuration and Power Interface (ACPI).
The MIC2544/48 is a cost-effective, highly integrated solution that requires few external components to satisfy USB and ACPI requirements.
Load current management features include a precision resistor-programmable output current-limit and a soft-start circuit which minimizes inrush current when the switch is enabled. Thermal shutdown, along with current-limit, protects the switch and the attached device.
The MIC2544/48's open-drain flag output is used to indicate current-limiting or thermal shutdown to a local controller. The MIC2548 has an additional internal latch which turns the output off upon thermal shutdown providing robust fault control. The enable signal is compatible with both 3V and 5V logic, and is also used as the thermal shutdown latch reset for the MIC2548.

MIC2550Universal Serial Bus Transceiver | Interface | 2 | Active | \*\*NOT RECOMMENDED FOR NEW DESIGNS\*\*\*
The MIC2550 is a single-chip transceiver that complies with the physical layer specifications for Universal Serial Bus (USB).
The MIC2550 supports full-speed (12Mbps) dual supply voltage operation (patent pending) and low-speed (1.5Mbps) operation.
A unique dual supply voltage operation allows the MIC2550 to reference the system I/F I/O signals to a supply voltage down to 2.5V while independently powered by the USB VBUS.
This allows the system interface to operate at its core voltage without addition of buffering logic and also reduce system operating current. |
