4. POWER SUPPLY
The power supply circuitry and the board layout are a very important part in the full
product design and they strongly reflect on the product overall performances, so the
requirements and the guidelines that will follow should be read carefully for a proper
design.
Power Supply Requirements
The external power supply must be connected to VBATT and VBATT_PA pads and must
fulfil the following requirements:
Power Supply
Value
Nominal Supply Voltage
3.8V
Operating Voltage Range
3.2 V - 4.2 V
Extended Voltange Range
2.6 V - 4.5 V
VBATT
min
2.7V
Table 10: Power Supply Requirements
Warning
: The range 2.6V - 3.2V can be used only if both USB and 2G
are disabled.
Warning:
The supply voltage of the modem must never exceed the
Extended Operating Voltage Range.
Wrong implementation of power supply guidelines described in this
document may result in module fault.
Note:
For PTCRB approval on the final products the power supply is
required to be within the “Normal Operating Voltage Range”.
