LTC1755/LTC1756
APPLICATIO S I FOR ATIO
The only possible next state is Idle/Deactivation which is
achieved by disabling the LTC1755/LTC1756 via the PWR
pin (i.e., PWR = DVCC).
The alarm indication can be cleared by rapidly cycling the
PWR pin. However, a new activation cycle will not begin
until VCC is or has dropped below approximately 1V.
ACTIVE
VCC = 3V or 5V (as determined by the 5V/3V pin)
RST = RIN, CLK = CIN
I/O, AUX2, AUX1, DATA, AUX2IN, AUX1IN = Ready for
data (after READY becomes low)
CARD = PRES ⊕ NC/NO
ALARM = H
FAULT TIMEOUT
Same as Active except:
The duration of a fault is being measured. If the fault
duration exceeds 5µs then the Alarm/Deactivation state
follows. If the fault duration is less than 5µs, then the
device is returned to the Active state.
