PWR_IND (Power Indica-
tor) notifies the module’s
on/off state (see Section
2.1.10).
PWR_IND is an open col-
lector that needs to be
connected to an external
pullup resistor. Low state
of the open collector indi-
cates that the module is
on. Vice versa, high level
notifies the power-down
mode. Therefore, the sig-
nal may be used to enable
external voltage regulators
which supply an external
logic for communication
with the module, e.g. level
converters.
Do not connect to V180.
