MIC2544/2548

Programmable Current Limit

High-Side Switch

General Description

Features

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.

• 2.7V to 5.5V input

• Adjustable current-limit up to 1.5A

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

• 75μA typical on-state supply current

• 1μA 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 the switch and the attached device.

• Thermal shutdown

• Thermal shutdown output latch (MIC2548)

• 2ms (slow) turn-on and fast turnoff

• Available with active-high or active-low enable

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.

Applications

• USB power distribution

• PCI bus power switching

• Notebook PC

• ACPI power distribution

• PC card hot swap applications

• Inrush current-limiting

The MIC2544 and MIC2548 are available in active-high

and active-low enable versions in the 8-pin SOIC

(small-outline integrated circuit) and 8-pin MSOP (micro-

small-outline package).
