Other Parts Discussed in Thread: ISO1540,
Dear Team,
Below is my customer's schematic design with PCA9306 and ISO1540.
Under some conditions, 3D3V_VCC, SDA and SCL would become floating when there is no connection at J2. But the enable pin of PCA9306 still has power(Remote_VCC). V_STBY has power also.
They would like to know is it possible SDA and SCL of J1 would have noise or drive to low?
Thank you.
Regards,
Jim
