That flag can drive a microcontroller GPIO or an LED to signal over-current, over-temperature, or reverse-current events. ## Protection set — adjustable current limit, over-temp, reverse current Fault protection includes an adjustable current limit (set with an external resistor), over-temperature shutdown, and reverse-current blocking. The adjustable limit lets you tailor the trip point to the load — useful for powering a USB peripheral that must not exceed 500 mA or 1.5 A, for example. The slew-rate controlled turn-on reduces inrush current into capacitive loads, which matters when the switch powers a bank of decoupling capacitors or a downstream regulator that would otherwise pull a glitch on the 5 V rail. ## Package and board-fit — hand-solderable 8-SOIC The supplier device package is 8-SOIC, and the part ships in tubes (standard for this package variant).","metaTitle":"MIC2549A-1YM USB Power Switch, 3A, 35mOhm, 8-SOIC","metaDescription":"Microchip MIC2549A-1YM high-side USB power switch, 3A output, 35mOhm Rds(on), adjustable current limit, active, RoHS3.
