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.
Best accuracy is obtained when:
Vdetect_ I= Vref_R – Vdet_I
Vdetect_R= Vref_I – Vdet_R
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.
Due to the BCB coating on the chip, qualification domain implies the chip must be glued.
