FAULT ZONE CONFIGURATION AND FAULT PROPAGATION
The LTC2978 has four FAULTB pins within two fault zones.
Each channel can pull FAULTB pins within its zone low.
Also, any channel can shutdown in response to FAULTB
pins within its zone, therefore, dependencies between any
channel(s) can be established. See Applications section
of the datasheet. See Figure below. Zone 0 and 1 are tied
together on the DC1360A through R9. Therefore, any
channel can shut off in response to any other channel
on the LTC2978. Additionally, each FAULTBz pin ties to a
FAULTn (n =1,2,3,4) line on the DC1360A which is bussed
Figure 13. Fault Zones and Fault Pins on DC1360A
to other DC1360A’s in a multiboard array. Therefore, it is
possible for any channel in an array to shutoff in response
to any other channel.
FAULTn lines are on p.2 DC1360A schematic J2, J3.
To disconnect Fault zone 0 from Fault zone 1, remove R9
on DC1360A.
