Q
In a new product we use the driver ADuM5230ARWZ and we have on some devices nooutput voltage (Viso).
Ours values of resistors for Vadj are Upper=0ohm and Lower=10kohm, can the
reason be? In datasheet I am not sure that we can use UPPER/LOWER=0/10?
Or have I to check the Vdd1 slew rate or other parameter?
A
If you use 0ohms for the upper resistor, and VDD1 goes above 5V, you could setthe duty cycle for the Viso to zero and shutdown Viso. I would recommend that
you change your resistors to 1K and 9K and see if the Viso is OK. Let me know
your feedback.
