Power On Timeout Errors
If the LTC2924 PGT is being used (not tied to ground) a
fault condition will be detected when the PGT pin goes
above ~1V. If this occurs during Power On, all of the OUT1-
OUT4 pins that are already high will be pulled low and the
FAULT pin will be pulled low.

Externally Commanded Faults
If an external circuit pulls the FAULT pin low, an external
fault condition is detected and all OUT pins will be pulled
low. After sensing the Externally Commanded Fault, the
LTC2924 will also pull down on the FAULT pin until the
conditions for clearing the fault condition exist (see Clear-
ing the Fault Condition).
