Operation beyond the specified operating conditions can affect device reliability.
4.3 Indicative current requirements
Table 8 lists examples of the total system supply current for a possible application.
Values in Table 8 are only provided for customer information as an example of typical power
requirements. Values are characterized on samples; actual power requirements can vary depending on the
firmware version used, external circuitry, number of SVs tracked, signal strength, type of start as well as
time, duration and conditions of tests.
