Abstract

La presente invencion muestra un sistema que tiene corriente de reposo reducida extraída de una fuente de energía. El sistema comprende un dispositivo que tiene un estado. Además, el sistema comprende un microcontrolador que tiene un modo de operacion activo y un modo de operacion dormir para sondear el estado del dispositivo durante el modo activo, iniciar una funcion en respuesta a un cambio en el estado durante el modo activo y para conservar la corriente de reposo extraída de la fuente de energía durante el modo dormir. De acuerdo con la presente invencion, el microcontrolador genera una señal de salida en un primer nivel de voltaje durante el modo activo y genera la señal de salida en un segundo nivel de voltaje durante el modo dormir. EL microcontrolador, además, comprende un detector para conmutar el microcontrolador desde el modo dormir el modo activo. Además, el sistema comprende un dispositivo de almacenamiento para cargar el primer nivel de voltaje durante el modo activo y para descargar a un tercer nivel de voltaje durante el modo dormir, para activar el detector y conmutar del modo dormir al modo activo.
