当输出过载时，VND5T050AK-E CSn输出会发生什么变化？

我们需要解决VND5T050AK-E双通道高端驱动器IC数据手册的不同意见。
我们同意，当您提供正常负载时，CSn输出充当电流源，其电流是通道n上实际输出电流的大部分。
但是，当您重置输出时，通道切换到故障模式，CSn输出执行其他操作。


我以为我读到某个地方，在出现故障后，CSn输出会产生一个可与任何有效电流读数区别开来的电压，但今天我在数据表的任何地方都找不到这个声明。数据表第5页的方框图显示了一个开关将CSn输出的源从“电流检测”放大器改变为标记为“VSenseH”的块。第17页上的表11表示Sense输出在接地短路后进入VSenseH。第12页的表9报告，当RSense = 3.9k时，故障状态下的VSenseH介于7.5和9.5 V之间。同一表格表明处于相同状态的ISenseH介于4.9＆amp;当VSense = 5 V时12 mA。我将此解释为在故障后CSn输出变为电压源，在这种情况下，语句4胜过声明5.我的同事认为CSn保持当前来源，在这种情况下声明4王牌声明5.有人知道吗？它是在数据表中的某个地方而我找不到它吗？
谢谢。

以下为原文





We need to settle a difference of opinion interpreting the data sheet for the VND5T050AK-E, dual channel high-side driver IC.
We agree that when you provide a normal load, the CSn output acts as a current source whose current is a rough fraction of the actual output current on channel n.
When you overload the output however, the channel switches into fault mode and the CSn output does something else.

• I thought I read somewhere that after a fault the CSn output assumes a voltage which is distinguishable from any valid current reading, but today I cannot find this statement anywhere in the data sheet.
• A block diagram on page 5 of the data sheet shows a switch changing the source of the CSn output from the ''Current sense'' amplifier to a block labeled ''VSenseH''.
• Table 11 on page 17 says the Sense output goes to VSenseH after a short to ground.
• Table 9 on page 12 reports that VSenseH in a fault condition lies between 7.5 and 9.5 V when RSense = 3.9k.
• The same table indicates that ISenseH in the same state is between 4.9 & 12 mA when VSense = 5 V.
  

• I interpret this to mean that after a fault the CSn output changes to a voltage source, in which case statement 4 trumps statement 5.
• My colleagues think that CSn stays a current source, in which case statement 4 trumps statement 5.
  

Does anybody know for sure? Is it somewhere in the data sheet and I just can't find it?
Thanks.
