3.2 INDIRECT MEASUREMENT

• Short pin 2 and 3 of I_SEL.

• DO NOT LEAVE DIGITAL INPUT PINS FLOATING, for instance:

– Short the DONE pin (4th pin of IO header) to GND

– Set PGOOD =1 (see Table 1)

• Connect a Digital Multi Meter, configured as the voltage meter, between TP1 and VDD test points.

• Read the voltage drop on the R_SH on the DMM.

• The current consumption is simply the voltage drop on R_SH, divided by 1Mohm.
