Hi,
My customer is confirming the input current value of VBATP pin when IGN pin is 0V.
Please see the attached file of page 1.
After IGN-OFF, the input current of VBATP pin has the change as the picture.
Time unit is seconds.
I confirmed customer circuit and output waveform.
Please see the attached file of page 2,3.
I think that TPS65381A-Q1 on customer board is standby state and there isn't current pass in circuit.
Could you confirm your test board this, please?
Best regards,
Shimizu
