Abstract

La presente materia se refiere en general a un circuito controlador integrado (101) para un sistema de iluminación de un vehículo (100). El circuito controlador integrado (101) integra un circuito de protección de sobrevoltaje transitorio, un circuito de filtrado y un circuito de protección de polaridad inversa con una sola unidad de control (106) para monitorear la corriente que se envía a la pluralidad de lámparas LED (LED1, LED2, LED3) proporcionadas en el vehículo y para controlar la iluminación de la pluralidad de lámparas LED (LED1, LED2, LED3) a través de la pluralidad de interruptores MOSFET (M1, M4, M2) controlando el voltaje de puerta de los interruptores MOSFET (M1, M4, M2). La integración se habilita mediante el uso de un solo circuito de controlador en lugar de múltiples controladores para cada lámpara en el vehículo. El driver integrado integra el accionamiento de cada una de las lámparas de forma independiente.The subject matter relates generally to an integrated driver circuit (101) for a vehicle lighting system (100). The integrated driver circuit (101) integrates a transient overvoltage protection circuit, a filtering circuit, and a reverse polarity protection circuit with a single control unit (106) to monitor the current that is sent to the plurality of LED lamps. (LED1, LED2, LED3) provided in the vehicle and to control the illumination of the plurality of LED lamps (LED1, LED2, LED3) through the plurality of MOSFET switches (M1, M4, M2) by controlling the gate voltage of the MOSFET switches (M1, M4, M2). The integration is enabled by using a single driver circuit instead of multiple drivers for each lamp in the vehicle. The integrated driver integrates the drive of each of the lamps independently.
