*2. Connect to a supply with
≥ 1.8mA drive current capability. If pull-up resistors Rup are connected to SCL, SDA, and SBN, the current
consumption increases by the amount flowing through the pull-up resistances only. The current component for each of the 3 pins is
given by Iup [mA] = VEN [V] / Rup [k
Ω].
