QS95 Current Measurement (3.3V Supply)

QS95 module current consumption can be determined via the integrated shunt resistor between Pin 49 and Pin 50.

To calculate the 3.3V supply current, measure the differential voltage across these pins and multiply the measured value by 10 (scaling factor: 10 A/V):

\[I_{\text{3.3V}} = 10 \times V_{\text{measured}}\]

Note

Quick Example: A measured voltage of \(100\text{ mV}\) across Pins 49 and 50 corresponds to a current consumption of \(1.0\text{ A}\).
