Hello, my name is Shoko Kitazawa.
I would like to use the HW variant of DRV8245.
Therefore, I have two questions regarding the DIAG function of the DRV8245-Q.
・1st point
In the data sheet, there is an item "8.3.3.4 DIAG".
“• Active State – HW variant only – Sets fault response to either Retry or Latch.”
It says that setting the DIAG pin to "RLVL5OF6" will "latch" the fault response in the active state.
Under what conditions will the outputs "OUT1 and OUT2" become active and the fault response "latched"?
・Second point
It says that setting the DIAG pin to "RLVL5OF6" disables off-state diagnostics in standby state.
However, the option to disable off-state diagnostics for HW variants only - high-side load use cases is not supported. In this case, the only way to disable off-state diagnostics is to set the DRVOFF pin to HIGH. and set the IN pin to LOW.''
Does this mean that the option to disable off-state diagnosis is not supported in PH/EN mode and PWM mode because it causes a high site load?
thank you.
