We have a issue with LTM4622. The output of 3.3V in the following schematic will have 1.1V level even the RUN2 is off. The output of V_1V2D is 0V when RUN1 is low.
This 'leaking' voltage on V_3V3D will cause problem, because the 'leaking' voltage' mess up other IC's power sequence requirement.
The RUN1 and RUN2 are pull down to 0.05V level in my PCB, and the V_SYS_D is 12V.
Any suggestion will be appreciated.
Thanks in advanced.
