TPS3613-01 current surge when switching from VDD to VBATT

Other Parts Discussed in Thread: TPS3613-01

I am working on a PCB with a TPS3613-01 supervisor IC to switch from 3.3V VDD to 3.0 V VBATT.  Shortly after the VDD power is removed I am seeing a current surge on VBATT.  The static current on VBATT is about 3 mA and the surge is up to about 6 mA.  The current surge appears to be 1 to 10 ms in duration.  I am in the process of measuring the current at VOUT.  In the meantime I am wondering whether the TPS3613-01 could be causing the current surge.


Thanks.
