TUSB8041-Q1: 关于TUSB8041-Q1 datasheet中的100小时的意思

Part Number: TUSB8041-Q1
Other Parts Discussed in Thread: TUSB8041

您好!TUSB8041-Q1 datasheet第15页8.3.7章节有如下说法:

Bus contention while VDD33 is powered up must be limited to 100 hours over the projected life-time of the device.

这句话应如何理解?意思是每隔100小时要重新给芯片来一次上电吗?

谢谢!

  • 您好,数据手册上有介绍:如果满足所有这些限制条件(其中一个条件条件即为上述100小时),则 VDD 或 VDD33电源可能会无限期加电,而另一个电源则不会加电。

    The TUSB8041-Q1 does not have specific power sequencing requirements with respect to the core power (VDD) or I/O and analog power (VDD33). The core power (VDD) or I/O power (VDD33) may be powered up for an indefinite period of time while the other is not powered up if all of these constraints are met:

    所以Bus contention while VDD33 is powered up must be limited to 100 hours over the projected life-time of the device.这句话翻译过来就是:

    VDD33加电时的总线争用必须在器件的预计使用寿命内限制为100小时,换句话说,在TUSB8041的预计使用寿命内,VDD33的加电时间限制为100小时。
