Hi all
We customer currently design Tablet, have USB charge function.
But sample run test 10 PCS tablet occur 3 PCS fault pin pull low, check inrush current is not over 1 A, so check schematic but looks OK.
PS. change LIM1 resistor 40 k ohm let current limit 0.5 A up to 1 A, this issue is fix
why Inrush current lower than 1 A, the fault pin occur pull low issue.....
