LM74900-Q1: sleep模式下,如果发生热关断,切换sleep或EN管脚可解除闭锁模式,这句话怎么理解?

Part Number: LM74900-Q1


过热锁存后,要解除锁存,是让sleep管脚置高,或EN管脚置低,就可以解除锁存是吗?但这样做,芯片也不在sleep模式下了吧?即进入正常工作模式或进入shutdown模式。

  • 您好,

    已经收到了您的案例,调查需要些时间,感谢您的耐心等待

    As an additional layer of protection, device also features thermal shutdown with latch off feature in SLEEP mode in case of any overheating of the device in SLEEP mode. To put the device out of the latch mode user has to toggle the SLEEP or EN pin.

    请您参考这个说明,要使器件退出锁存模式、用户必须切换 SLEEP 或 EN 引脚。

    是的。
