1. Empieza con el objetivo Ejemplo: “Estoy creando un módulo de control para una bomba de aire de 24 V en una máquina CNC láser. El circuito debe encender y apagar la bomba según la señal FAN que viene de la tarjeta de control (3.3 V o 5 V).” 2. Explica los requerimientos La bomba trabaja a 24 V y hasta 2 A. El control debe ser con un MOSFET N–channel en conmutación. Debe incluir protección contra picos y ruidos eléctricos. Se deben mostrar indicadores LED (encendido, funcionamiento, error). 3. Lista de funciones que quieres en el diseño Protección: fusible, diodo flyback, TVS, snubber RC. Control: MOSFET con resistencia de gate y pull-down. Filtrado: capacitores cerca de la bomba. Indicadores LED: Azul: energía 24 V presente. Verde: bomba activa. Rojo: error o apagado. 4. Explica la lógica de funcionamiento (qué debe pasar) Cuando la fuente 24 V se conecta → LED azul enciende. Cuando la señal FAN activa el MOSFET → bomba enciende + LED verde enciende. Cuando la bomba está apagada → LED rojo puede encender (opcional). Si ocurre sobrecorriente → el fusible abre el circuito. 5. Diagrama de bloques sencillo (texto) [FUENTE 24V] -- [FUSIBLE] --+--> [BOMBA] --> [MOSFET] --> GND | +--> [LED Azul] --> GND [SALIDA FAN] --> [Res 100Ω] --> [Gate MOSFET] [Gate MOSFET] --> [Pull-down 100kΩ a GND] [Protecciones: Diodo, TVS, RC, Capacitores en paralelo con la bomba]
