MIC2544/2548
Programmable Current Limit
High-Side Switch
General Description
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.
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).
