bq76pl455芯片 启用Squeeze 电阻就可以进行开路检测
In the example in Figure 24, the Squeeze resistor is enabled for (across) VSENSEn-1 to VSENSEn. This will
cause the apparent voltage seen by the comparators for cell n–1 and cell n+1 to increase. For the cell voltage of
cell n, which in this example is approximately 3.6 V, there will be an additional drop on the internal lines going to
the window-comparator block (but not to the AFE) of (3.6 V / 5K × 100 × 2) = approximately 144 mV. This will
also show up as an increase of approximately 72 mV on the cells above and below the cell being squeezed.
Larger input resistors, such as 1 kΩ, will dominate this error source and may result in unexpected trips of the
window comparators, depending on the threshold settings, and will change the manner in which the calculations
suggested in this example are made.
根据这段内容，连接Squeeze resistor，窗口比较器可以检测到压降，AFE也能检测到72mV压降等等。但是尝试过后好像又不对。
1.求解，bq76pl455芯片开路检测是如何工作的，如何判断导线开路。
窗口比较器Comparator电压可以检测到吗？
2. 还有无论我怎么 进行测试，都无法触发CMPOV和CMPUV 。这又是怎么回事。。Comparator这个东西究竟要怎么理解？？
求诸位解答。谢谢！！！！
