10 / 12 page 10 LTC1755 APPLICATIONS INFORMATION Figure 4. LTC1755 State Diagram DEACTIVATION NO FAULT FAULT 1755 F04 POWER OFF IDLE DEACTIVATION ALARM ACTIVE FAULT TIMEOUT PWR = DVCC PWR = DVCC PWR = 0V PRES ≠ NC/NO FAULT > 5 µs or PRES ≠ NC/NO 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 = 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 5 µs then the Alarm/Deactivation state follows. If the fault duration is less than 5 µs, then the device is returned to the Active state. State Definitions IDLE/DEACTIVATION VCC, RST, CLK, I/O AUX2, AUX1 = L READY, ALARM, DATA, AUX2IN, AUX1IN = Z CARD = PRES ⊕ NC/NO Once the LTC1755 enters the Idle/Deactivation state the deactivation sequence begins. The deactivation sequence will continue until VCC is discharged to approximately 1V. An activation command (PWR = 0V) will only be acknowl- edged once this occurs. |
