说明(续)

当发生去饱和故障时,器件会通过隔离隔栅发送故障信号,以将输入端的 FLT 输出拉为低电平并阻断隔离器的输入。静音逻辑在软关断期间激活。FLT 的输出状态将被锁存,并只能在 RDY 引脚变为高电平后通过 RST 输入上的低电平有效脉冲复位。

如果在由双极输出电源供电的正常运行期间关断 IGBT,输出电压会被硬钳位为 VEE2。如果输出电源为单极,那么可采用有源米勒钳位,这种钳位会在一条低阻抗路径上灌入米勒电流,从而防止 IGBT 在高电压瞬态状态下发生动态导通。

栅极驱动器是否准备就绪待运行由两个欠压锁定电路控制,这两个电路会监视输入端和输出端的电源。如果任意一端电源不足,RDY 输出会变为低电平,否则该输出为高电平。

ISO5852S 采用 16 引脚小外形尺寸集成电路 (SOIC) 封装.此器件的额定工作环境温度范围为 -40°C 至 +125°C。
