MIC2544/48
Programmable Current-Limit High-Side Switch
Features 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 are cost-effective, highly
integrated solutions that require 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”)
75 ОјA Typical On-State Supply Current
1 ОјA Typical Off-State Supply Current
120 mΩ Maximum On-Resistance
Open-Drain Fault Flag
Thermal Shutdown
Thermal Shutdown Output Latch (MIC2548)
2 ms (Slow) Turn-On and Fast Turn-Off
Available with Active-High or Active-Low Enable Applications Load current management features include a precision
resistor-programmable output current-limit and a
soft-start circuit that minimizes inrush current when the
switch is enabled. Thermal shutdown, along with
current-limit, protects the switch and the attached …
