MIC2546/2547

Dual Programable Current Limit Switch

General Description

Features

The MIC2546 and MIC2547 are integrated high-side dual

power switches optimized for low loss dc power switching

and other power management applications, including

Advanced Configuration and Power Interface (ACPI). The

MIC2546/47 is a cost-effective, highly integrated solution

that requires few external components to satisfy USB and

ACPI requirements.

• 2.7V to 5.5V input

• Adjustable current-limit up to 1.5A

• Reverse current flow blocking (no “body diode”)

• 100μA typical on-state supply current per channel

• 2μA typical off-state supply current

• 120mΩ maximum on-resistance

• Open-drain fault flag

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 theswitch and the attached device.

• Thermal shutdown

• Thermal shutdown output latch (MIC2547)

• 2ms (slow) turn-on and fast turnoff

• Available with active-high or active-low enable

The MIC2546/47’s open-drain flag outputs are used to

indicate current-limiting or thermal shutdown to a local

controller. The MIC2547 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 MIC2547.

Applications

• USB power distribution

• PCI Bus Power Switching

• Notebook PC

• ACPI power distribution

• PC card hot swap applications

• Inrush current-limiting

The MIC2546 and MIC2547 are available in active-high

and active-low enable versions in 16-pin TSSOP and SOP

packages.

Micrel’s web site at www.micrel.com.

• Ideal for dual supply applications
