VN5050AJ CS_DIS not working - again

[rkager]

As in https://community.st.com/t5/power-management/vn5050aj-cs-dis-not-working/m-p/632201#M10745 we now have added seriel diodes for every chip, but it is still not disabling his Current_Sense Output altough the CS_DIS Pin is above 3V.  The CS_DIS-1 Signal is comming from an 74HC138 so there is just always on VN5050 selected. The same principial is working fine on VND5160. 

Any advice would be appricatied

We have found the issue. The dual chip version is mounted on the PCBs. As the pinning is nearly the same, the output is working but the current sense / CS_DIS has off course a strange behavior.
