Shutdown
: In the shutdown state, all voltage forms are applied, but power consumption is
approximately 5 mW. In the shutdown state, no functions are available, but it is possible to
transition to the on state via the start-up sequence defined in
. The shutdown sequence
shown in
is the recommended transition back to the shutdown state. It is also possible
to transition between shutdown and on states via software commands, as further defined in the
software IDD.
•
Overtemp
: The Overtemp state is automatically entered when the Lepton senses that its
temperature has exceeded approximately 80 °C. Upon entering the Overtemp state, Lepton
enables a
“sh
utdown imminen
t”
status bit in the telemetry line and starts a 10-second counter. If
the temperature of the Lepton falls below 80 °C before the counter times out, the
“
shutdown
immin
ent”
bit is cleared and the system transitions back to the on state. If the counter does time
out, Lepton automatically transitions to the standby state.
Power sequencing is as shown in
