MIC2546/2547

Dual Programable Current Limit Switch

General Description

Features

The MIC2546 and MIC2547 are integrated high-side dual

•

2.7V to 5.5V input

power switches optimized for low loss dc power switching

•

Adjustable current-limit up to 1.5A

and other power management applications, including

•

Reverse current flow blocking (no “body diode”)

Advanced Configuration and Power Interface (ACPI). The

•

100μA typical on-state supply current per channel

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

•

2μA typical off-state supply current

that requires few external components to satisfy USB and

ACPI requirements.

•

120mΩ maximum on-resistance

Load current management features include a precision

•

Open-drain fault flag

resistor-programmable output current-limit and a soft-start

•

Thermal shutdown

circuit which minimizes inrush current when the switch is

•

Thermal shutdown output latch (MIC2547)

enabled. Thermal shutdown, along with current-limit,

•

2ms (slow) turn-on and fast turnoff

protects theswitch and the attached device.

•

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

Applications

which turns the output off upon thermal shutdown

providing robust fault control. The enable signal is

•

USB power distribution

compatible with both 3V and 5V logic, and is also used as

•

PCI Bus Power Switching

the thermal shutdown latch reset for the MIC2547.

•

Notebook PC

The MIC2546 and MIC2547 are available in active-high

•

ACPI power distribution

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

•

PC card hot swap applications

packages.

•

Inrush current-limiting

Data sheets and support documentation can be found on

•

Ideal for dual supply applications

Pin Function

Input A: Output A MOSFET drain. Also supplies internal circuitry.

Switch A (Output): Output A MOSFET source. Pins 2 and 16 must be externally

connected.

Enable A (Input): Logic-compatible enable input. Active- activelow (–2). High

input >1.7V typical; low input <1.5V typical. MIC2547 only: Also resets thermal

shutdown latch.

Not internally connected.

Fault Flag A (Output): Active-low, open-drain output. Indicates overcurrent or

thermal shutdown conditions. MIC2547 only: latched low on thermal shutdown.

Ground. Both pins must be connected to GND.

Current Limit Channel B: Sets current-limit threshold using an resistor, R
