Title (EN) LIGHT-EMITTING ELEMENT DRIVE DEVICE
(FR) DISPOSITIF D'EXCITATION D'ÉLÉMENT ÉLECTROLUMINESCENT
(JA) 発光素子駆動装置
Abstract:
(EN) This light-emitting element drive device comprises: a transistor control unit for driving and controlling a transistor connected to a light-emitting element; an output ground detection unit for outputting an output ground detection signal in accordance with the voltage level at a connection point between the light-emitting element and the transistor; a stop control unit for stopping the drive of the transistor when the output ground detection signal indicates output ground; and a mask signal generation unit for generating a mask signal that masks the output ground detection signal on device startup.
(FR) L'invention porte sur un dispositif d'excitation d'élément électroluminescent qui comprend : une unité de commande de transistor pour exciter et commander un transistor connecté à un élément électroluminescent ; une unité de détection de masse de sortie pour délivrer un signal de détection de masse de sortie en fonction du niveau de tension au niveau d'un point de connexion entre l'élément électroluminescent et le transistor ; une unité de commande d'arrêt pour arrêter l'excitation du transistor lorsque le signal de détection de masse de sortie indique la masse de sortie ; et une unité de génération de signal de masquage pour générer un signal de masquage qui masque le signal de détection de masse de sortie au démarrage du dispositif.
(JA) 発光素子に接続されたトランジスタを駆動制御するトランジスタ制御部と、前記発光素子と前記トランジスタとの接続点の電圧レベルに応じた出力地絡検出信号を出力する出力地絡検知部と、前記出力地絡検出信号が出力地絡を示す場合に前記トランジスタの駆動を停止させる停止制御部と、起動の際に前記出力地絡検出信号をマスキングするマスク信号を生成するマスク信号生成部と、を備える発光素子駆動装置としている。
