Power Supply
The power supply circuitry and board layout are a very important part in the full product design
and they strongly reflect on the product overall performances, hence read carefully the
requirements and the guidelines that will follow for a proper design.
5.1.
Power Supply Requirements
The external power supply must be connected to VBATT & VBATT_PA signals and must
fulfill the following requirements:
POWER SUPPLY
Nominal Supply Voltage
3.8 V
Normal Operating Voltage Range
3.40 V÷ 4.20 V
Extended Operating Voltage Range
3.20 V÷ 4.50 V
NOTE:
The Operating Voltage Range MUST never be exceeded; care must be taken in order to fulfil
min/max voltage requirement.
NOTE:
Overshoot voltage (regarding MAX Extended Operating Voltage) and drop in voltage
(regarding MIN Extended Operating Voltage) MUST never be exceeded;
The “Extended Operating Voltage Range” can be used only with completely assumption and
application of the HW User guide suggestions.
