APPLICATIO S I FOR ATIO
PACKAGE DESCRIPTIO
The only possible next state is Idle/Deactivation which is
achieved by disabling the LTC1755/LTC1756 via the PWR
pin (i.e., PWR = DV

PWR pin. However, a new activation cycle will not begin
until V

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