Microchip MIC2544-1YM-TR, High Side Power Switch IC 8-Pin, SOIC

The Microchip MIC2544 series 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 are cost-effective, highly integrated solutions that require few external components to satisfy USB and ACPI requirements. The 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 device.

Input range is from 2.7 V to 5.5 V
Adjustable current-limit up to 1.5A
Reverse current flow blocking
Typical on-state supply current of 75 μA
Typical off-state supply current of 1 μA
Maximum on-resistance of 120 mΩ
