4.3 Indicative power requirements

Table 9 lists examples of the total system supply current for a possible application.

requirements. Values are characterized on samples; actual power requirements can vary

depending on FW version used, external circuitry, the number of SVs tracked, signal strength,

type of start as well as time, duration and conditions of test.
