DM3725 and TPS65950 power down(shut down) sequence

Hi,

We are using DM3725 and TPS 65950 based customized device and facing some issues with power down(shut down).

We tried to shut down device by writing 1 to TPS65950 register P1_SW_EVENTS (0x46), with this device is shutting down but we are getting VBAT current 3mA.

We also tried by configuring all regulators  REMAP registers to 0 but no luck, observation is same 3 mA current.

Can anyone let us know whatever we followed to shutdown is correct or not ?

If SW step is correct then how we can debug HW level, which are components  or test points we need to test to find out HW leakage current.

Thanks,

Raviraj
