Question about PCB layout of 2 x ADP2442

Hi All,

Two ADP2442s are mounted on our customer's  PCB but they don't work normally.They stop to work during start-up.

I have attached the customer's schematic and layout. Both 3.3V_GND and 5V_GND are not separated on the layer 2.

Do you think that it could be the cause of this start-up issue?

Regards,

Kazu
