The switch is active-high, non-inverting, and requires no external Vcc supply — the gate drive is derived from the load voltage. ## Protection and flagging Built-in fault protection covers current limiting (adjustable via an external resistor) and overtemperature shutdown — the switch latches off under overcurrent or thermal fault, and the open-drain Status Flag output signals the condition to the host controller. The switch is rated for continuous output at 1.5 A, but the actual current limit is set by the external resistor — the 80 mOhm typical Rds(on) keeps conduction losses low enough that the package can dissipate the heat without forced airflow at moderate ambient temperatures.","metaTitle":"MIC2544A-1YMM-TR USB Power Switch, 1.5A, 80mOhm, 8-MSOP","metaDescription":"Microchip Technology MIC2544A-1YMM-TR USB high-side switch, 1.5A max output, 80mOhm typ Rds(on), active production, ROHS3 compliant.
