LED Driver/Monitor

GENERAL DESCRIPTION The AD8240 LED driver/monitor, in combination with an external transistor, supplies a constant 12 V to drive LED lamps. This allows cost-effective LED lamp monitoring and short-circuit protection. The output is regulated at 12 V when the supply voltage is between 12.5 V and

LED 驱动器/监控器

AD8240是一款LED驱动器/监控器，与外部晶体管结合使用可提供恒定的12 V电压，用于驱动LED灯。它可提供高性价比的LED灯监控和短路保护。当电源电压介于12.5 V与27 V之间时，输出稳定在12 V。\n\n 可以利用CMOS兼容、电平相关的数字输入对LED亮度进行PWM控制。当PWM输入为高电平时，VO开启；当PWM输入为低电平时，VO关闭。AD8240的PWM设计工作频率最高可达500 Hz，典型PWM范围为5%至95%。\n\n LED开路检测通过测量LED开路所引起的LED灯电流变化来实现。测量时使用内部高端电流检测放大器，可放大外部分流电 • PWM 输入用于LED亮度控制\n\n• LED开路检测\n\n• 过流锁定保护\n\n• 恒压稳压输出\n\n• 稳压范围：12.5 V至27 V;
