... Micrel, Inc. Functional Description The MIC2544 and MIC2548 are high-side N-channel switches available with active-high or active-low enable inputs. Fault conditions turn-off or inhibit turn-on of the output transistor and activate the open-drain error flag transistor making it sink current to ground. Input and Output IN is the power supply connection to the logic circuitry and the drain of the output MOSFET ...

... C transient surge pass for 100μs without tripping the overcurrent flag (FLG). USB Power Distribution The MIC2544 is ideal for meeting USB power distribution requirements. Figure 4 depicts a USB Host application. RSET should be set to a value providing a current-limit >500mA. The accurate current-limit of the MIC2544 will reduce power supply current requirements ...
