- Higher isolation voltage than Si8641 (vs Si8641BB-B-IS1)
Design Notes
For optimal performance, place 0.1 µF decoupling capacitors close to VDD1 and VDD2 pins (pin 1 and pin 16). Use a ground plane on both sides of the isolation barrier, but ensure the isolation gap is maintained to preserve the rated isolation voltage. Keep the PCB trace length between the isolator and the connector as short as possible to minimize EMI.
Maintain a minimum creepage distance of 8 mm between the input and output sides of the isolator on the PCB to meet safety standards for 3750 Vrms isolation. Avoid routing high-speed signals parallel to the isolation barrier to reduce crosstalk. Use separate ground planes for side 1 and side 2, connected only at the system star point.
Do not exceed the absolute maximum supply voltage of 6V on VDD1 or VDD2. Ensure that the input signals do not exceed the supply voltage by more than 0.3V. When using the fail-safe feature, note that the outputs will go to a predefined state when input power is lost; design your system to handle this state appropriately.
Compliance Information
RoHS compliant per JLCPCB listing. Not AEC-Q100 qualified; for automotive, consider ADUM141E1WBRQZ-RL7 which may have automotive grade.
