ALARM/DEACTIVATION
Same as Idle/Deactivation except:
ALARM = L
The only possible next state is Idle/Deactivation which is
achieved by disabling the LTC1755 via the PWR pin
(i.e., PWR = DV
CC
).
The alarm indication can be cleared by rapidly cycling the
PWR pin. However, a new activation cycle will not begin
until V
CC
is or has dropped below approximately 1V.

FAULT TIMEOUT
Same as Active except:
The duration of a fault is being measured. If the fault
duration exceeds 5
μ
s then the Alarm/Deactivation state
follows. If the fault duration is less than 5
μ
s, then the
device is returned to the Active state.

Once the LTC1755 enters the Idle/Deactivation state the
deactivation sequence begins. The deactivation sequence
will continue until V
CC
is discharged to approximately 1V.
An activation command (PWR = 0V) will only be acknowl-
edged once this occurs.
