MC33771B - MEAS_XXX voltage value to convert

[Patrick_Pavle]

Dear Community, 

I have read out the MEAS_STACK register and the MemoryDatat contains the value: 0xA299.
How can I convert the value into a usable voltage value?

best regards,

Patrick

Hello Patrick,

The stack voltage calculation is explained in our AN12084, chapter 7.2.2:

So in your case MEAS_STACK[14:0] = 0x2299 = 8857

then Vstack = 8857 * 2.44141 = 21624 mV = 21.624 V
