CJ950

18路低边功率开关

应用和技术摘要

CJ950

CJ950为18路低边功率管提供短路保护。所有通道均通过微秒通道(MSC)接口进行控制并受到持续监控。

  • OUT1和OUT3标称值为3A,最大为8A持续200秒
  • 更高钳位能量的OUT9和OUT10用于执行器控制
  • 可并联的功率级

产品优势

  • 微秒通道(MSC)接口
  • 每个输出通道的广泛诊断功能:电池短路,接地短路,开路负载,过热警告
  • 当VDD太低或太高时,功率管被禁用。当MSC监控检测到错误,μC复位有效或复位引脚被拉低时,情况也是如此。

受保护的输出功率级

所有输出的钳位电压为55V(典型值)
