J37
1-2
The VDD_HV_A domain is routed to the collector
terminal in order to supply the NPN external Ballast
transistor for the V15_MCU domain.
2-3
The VDD_HV_B domain is routed to the collector
terminal in order to supply the NPN external Ballast
transistor for the V15_MCU domain.
Default
closed
OPEN
The VDD_HV_A and VDD_HV_B domains are isolated
to supply the NPN external Ballast transistor for V15.
J360
1-2
The VDD_HV_A domain is directly routed the V15_MCU
domain.
2-3
The FS26_VCORE domain [+1.5V] is directly routed the
V15_MCU domain.
