Recommended external resistors assembly
100kΩ resistors in parallel with Vdet_I, Vref_I, Vdet_R and Vref_R pads are recommended to
provide the best behaviour in the whole operating temperature range.
As the voltage detection is the difference between Vref_X and Vdet_X (X= I or R), the
external resistor value should be identical on these ports.
For information, a variation of 2% leads around 1mV variation of detected voltage.
ESD protections are implemented on Vdet_I, Vref_I, Vdet_R and Vref_R accesses.
The DC connections (DC_R & DC_I) do not include any decoupling capacitor in package,
therefore it is mandatory to provide a good external DC decoupling on the PC board, as
close as possible to the package.
