At 3 A the conduction loss is I²R = 0.36 W — the 8-SOIC copper pad area under the die sets the thermal budget; a 1 oz pour on the PCB keeps the junction below the 85 °C ambient limit. The supply (Vcc/Vdd) range is the same, so the same rail can drive the gate drive and the load. Fault protection includes adjustable current limiting, open-load detection, over-temperature shutdown, and under-voltage lockout (UVLO). The Status Flag output signals a fault condition to the host controller — useful for hot-swap or USB port power management where the system needs to know when a port is overloaded. ROHS3 compliant — no restricted substances per the latest EU directive.","metaTitle":"MIC2043-1YM High-Side Power Switch, 3A, 8-SOIC, Active","metaDescription":"MIC2043-1YM high-side power switch, 3A max output, 40 mOhm Rds(on), 1.6V-5.5V load range, 8-SOIC.
