Lines of BATT+ and GND
must be connected in par-
allel for supply purposes
because higher peak cur-
rents may occur.
Minimum voltage must not
fall below 3.0V including
drop, ripple, spikes and not
rise above 4.5V.
BATT+
BB
and BATT+
RF
require an ultra low ESR
capacitor respectively of
150µF. If using Multilayer
Ceramic Chip Capacitors
(MLCC) please take DC-
bias into account. Note
that minimum ESR value is
advised at <70mΩ.
Note: The module’s nor-
mal voltage range for oper-
ation lies between 3.0V
and 4.5V. For USB opera-
tion, 3.0V-4.5V is also rec-
ommended.

V180 should be used to
supply level shifters at the
interfaces.
Note: V180 is not back
powering protected.
Wrong usage may back
power the module which is
forbidden.
If unused keep line open.
Test point recommended.
