MIC2545A/2549A

Programmable Current Limit High-Side Switch

General Description

Features

The MIC2545A and MIC2549A are integrated high-side

power switches optimized for low loss DC power switching

and other power management applications, including Ad-

vanced Configuration and Power Interface (ACPI). The

MIC2545A/49A 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 3A

• Reverse current flow blocking

• 90µA typical on-state supply current

• 1µA typical off-state supply current

• 50mΩ maximum on-resistance

• Open-drain fault flag

• Thermal shutdown

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 adjustable current-

limit, protects the switch and the attached device.

• Thermal shutdown output latch (MIC2549A)

• 2ms (slow) soft-start turn-on, fast turnoff

• Available with active-high or active-low enable

Applications

The MIC2545A/49A’s open-drain flag output is used to indi-

catecurrent-limitingorthermalshutdowntoalocalcontroller.

The MIC2549A 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, andisalsousedasthethermalshutdownlatchresetfor

the MIC2549A.

• USB power distribution

• PCI Bus Power Switching

• Notebook PC

• ACPI power distribution

• PC card hot swap applications

• Inrush current-limiting

The MIC2545A and MIC2549A are available in active-high

and active-low enable versions in 8-pin DIP, SOIC, and

TSSOP packages.
