According to the content of the configuration parameter ‘Fan_Outage_Detect_cfg’, the LDM will either perform full stall/outage detection or not. In case stall/outage detection must be performed (Fan_Outage_Detect_cfg = 0x01), the LDM will monitor the feedback line(C16) of the fan.
|State of the Fan Feedback Line |Voltage Range |Operational State of the Fan|
|Logical Low |<1.72V |Normal Operation|
|LogicalHigh |>3.32&<5V |Stall|
The LDM can process this type of feedback signal only.
