Si84xxISO-EVB UG
3. Hardware Overview and Setup
2
The Si84xxISO evaluation board comes populated with an Si8400 (isolated I
C), Si8421 (2-channel digital isolator,
one forward, one reverse), Si8442 (4-channel digital isolator, two forward, two reverse), and Si8463 (6-channel
digital isolator, three forward, three reverse) installed. The Si84xx5kVISO-EVB adds the Si8420 and Si8422 5 kV
family members. The board is designed to be powered from two separate 5 V supplies (500 mA) that power all the
isolators on the board. Power is applied to the board before evaluating any isolated channel. Power is applied to
the Si84xxISO-EVB by connecting 5 V supplies to the topmost supply terminals (VDD1 and GND1, VDD2 and
GND2). Power is applied to the Si84xx5kVISO-EVB by applying 5 V supplies to the topmost and middle power
terminals (VDD1 and GND1, VDD2 and GND2). The top power terminals power the 2.5 kV isolators. The middle
power terminals power the 5 kV isolators. Supplies as low as 2.7 V can be used. If a user wants to evaluate an
isolator other than the ones populated, this can be accomplished by removing the footprint-compatible device
installed on the evaluation board and replacing it with the desired isolator device. Figures 3 and 5 provide
silkscreen overviews of the boards.
