Operation beyond the specified operating conditions can affect device reliability.
4.3 Indicative power requirements
Table 9 lists examples of the total system supply current for a possible application.
☞
The values in Table 9 are provided for customer information only, as an example of typical power
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.
