The input is non-inverting with an On/Off interface, and the output configuration is a single N-channel MOSFET with a 1:1 input-to-output ratio. ## Fault protection set and status flag The MIC2043-2YM integrates adjustable current limiting, open-load detection, overtemperature shutdown, and undervoltage lockout (UVLO). The status flag output signals when the switch is in fault — useful for a microcontroller to log or retry the load. The slew-rate controlled turn-on limits inrush current into capacitive loads, which prevents the upstream supply from drooping. The 8-SOIC package (0.154\" width, 3.90mm body) is a standard footprint for automated assembly.","metaTitle":"MIC2043-2YM High-Side Switch, 3A, 40mOhm, 8-SOIC","metaDescription":"Microchip Technology MIC2043-2YM single-channel high-side power switch. 3A max output, 40 mOhm Rds(on), 1.6V-5.5V, 8-SOIC.
