6. Power Supply
The power supply circuitr y and board layout are a very important part in the full
pr oduct design and they strongly reflect on the product overall per formances, hence
read carefully the requirements and the guidelines that will follow for a proper
design.
6.1. Power Supply Requirements
POWER SUPPLY
Nominal Supply Voltage
3.8 V
Nor mal Oper ating Voltage Range
3.4 V÷ 4.20 V
Extended Operating Voltage Range
3.22 V÷ 4.50 V
NOTE:
The Oper ating Voltage Range MUST never be exceeded; care must be taken in order
to fulfil min/max voltage requir ement.
NOTE:
Overshoot voltage (regarding MAX Extended Operating Voltage) and dr op 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.
