公司介绍
FAN41501 是一款数字控制器,用于重要接地故障断路器 (GFCI) 部件的定期功能检测。它结合现有的安森美半导体 GFI 控制器,对 GFCI 控制器、电磁阀、传感变压器、SCR 和其他不同部件的功能允许进行定期检测,而不用中断为负载提供的电源或者损害正常的 GFCI 保护功能。如果 FAN41501 检测到故障 GFCI 部件,则会生成一个寿命结束 (EOL) 故障信号,可用于拒绝电源和/或在拒绝电源后自动复位。首次应用交流电源时,内部计时器则会启动一个一秒的检测周期。在此初始检测周期之后,内部计时器则每 90 分钟启动一个检测周期。在检测周期期间,FAN41501 会模拟一个接地故障,并监控重要的 GFCI 部件。如果 FAN41501 检测到部件故障,则会验证该故障几次,以防发出错误的 EOL 信号。在检测周期期间不会禁用或破坏正常的 GFCI 保护。FAN41501 包括 5 V 并联稳压器、一秒计时器、90 分钟计时器、数字控制逻辑、检测比较器以及 EOL 驱动器输出。FAN41501 结合 FAN4149 等 GFCI 控制器,提供了一个完整的 UL943 GFCI 功能,具有自动监控功能、低系统功耗,外部部件数目也非常少。该 6 引脚 SuperSOT™ 封装实现了一个低成本的紧凑设计和布局。
