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 overall performance of the product 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 & VBATT_PA signals 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 15

:

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”.
