3.4.4 Power Consumption Test Results

The demonstration results indicate that the location of the LAUNCHXLCC1352R1 is near the base board and IWRL6432FSPEVM.

Table 3-3 lists the results of the power measurements. The current was measured at the input of the IWRL6432FSPEVM and 18650 Li-ion battery.

Table 3-3 Power Consumption
MEASURE DEVICE MIN CURRENT AVG CURRENT MAX CURRENT
18650 Li-ion battery 7.33 mA 33.37 mA 160.20 mA
IWRL6432FSPEVM(1) 0.59 mA 27.82 mA 155.27 mA
(1) IWRL6432FSPEVM is optimized in low-power consumption mode. For example, LED and some pullups are removed during the power consumption tests.
