Hello, we encountered some problems when using tps92520.
We detected the LED open circuit according to the 3 conditions mentioned in the manual. During the actual test, it is found that the values of each STATUS1 and STATUS2 register are randomly changing.
There are 7 cases listed above. For example, if the 6th case above occurs, we cannot judge whether the circuit is open.
Q1: please help us provide an algorithm or idea for detecting LED, thanks;
Q2: Is it okay if we only test the content of the CHxCOMPOV as a judgment condition?
Q3: if we only test the VCSNx ADC data to judge the LED open condition, can we?
