If L6460 is not configured as slave device a current source I
OUT
will be active on this pin,
while the current sink I
INP
will be disabled. If L6460 is configured as a Slave device, the
current sink I
INP
will be active until nAWAKE pin is detected high for the first time; after that
both current sources I
INP
and I
OUT
will be disabled and the nAWAKE pin can be considered
as a digital input.
Here below is reported the nAWAKE pin simplified schematic.
