ADM1066 delay time

Dear ADI Expert,

I would like to clear ADM1066 issues.

When I setup Sequencing engine in the SuperSequencer tools , the Timer delays can be set from 10 μs to 400 ms, the delay time is effect by output delay or input delay?

If I setup a state but didn’t triggered any sequence or timout, have any state machine to retry or it will be hold?

What kind of status before setup the PDOx? Is it high-Z or pull up/down status?

Best Regards.

Ray.

    Hi Ray,

    There are two timers in each state that can be configured from 0.1ms to 400ms. One is in the sequence action and other is in timeout action.

    The sequence action timer waits for X ms after a voltage or signal at the input is stable before jumping to the exit state. If the voltage or signal falls below the thresholds within that time it will not jump to the next state. Example:

    If the VX1 voltage is stable (no OV or UV fault) for 100ms then the sequence will jump to State 6.

    The timeout action timer waits for X ms before jumping to the exit state. Example:

    If the sequence or monitor action did not become true within the time set in the timeout action, in that case after the timeout time the sequence will jump to the exit state defined in the timeout action.

    Timeout will automatically trigger after the configured timeout value. If the timeout is disabled and the sequence condition didn't trigger in that case it will remain in that state until the sequence condition becomes true.

    As the input supply to the ADM1066 ramps up on VPx or VH, all PDOx pins behave as follows:

    Input supply = 0 V to 1.2 V. The PDOs are high impedance

    Input supply = 1.2 V to 2.7 V. The PDOs are pulled to GND by a weak (20 kΩ) on-chip pull-down resistor.

    Supply > 2.7 V. Factory-programmed devices continue to pull all PDOs to GND by a weak (20 kΩ) on-chip pull-down resistor. Programmed devices download current EEPROM configuration data, and the programmed setup is latched. The PDO then goes to the state demanded by the configuration. This provides a known condition for the PDOs during power-up.
