Another aspect of protecting the integrity of the system
is to ensure that a new command cannot be received
and executed until the previous command execution is
finished.
Figure 24. Exclusion of Overlapping Commands
Figure 24 illustrates the operation of the FAN324x with
overlapping commands. The IN2 input signal is being
received while the previous command on channel one is
still being executed. It is signified by the fact that OUT1
is still LOW when the rising edge of the IN2 signal
arrives. Because the previous command is still active,
the IN2 signal is discarded by the input protection logic
of the FAN324x. That means that once the FAN324x is
committed to an output pulse, it ignores the other input
(except the EN input, which is the most dominant input
of the device).
c)
XOR Input Protection
The XOR protection implemented in the FAN324x
devices prohibits output pulses when two qualified input
signals have been received at the same time. The XOR
protection works when both inputs are asserted together
or a second qualified input is received while the first one
is being qualified. The two cases of the XOR protection
are illustrated in Figure 25 and Figure 26.
Figure 25. Simultaneous Insertion of Two
Qualified Inputs
Figure 26. Overlapping Qualified Inputs Case
The XOR protection prevents simultaneous drive signals
being delivered to the two coils of the relay and is an
important feature of the device.

Relay Drive Outputs (OUT1 and OUT2 Pins)
The actual relay is driven through the dedicated drive
outputs
of
the
FAN324x.
These
outputs
utilize
monolithic MOSFET power devices, in an open-drain
configuration, which are capable of handling the voltage
level and drive current required to energize the relay
coils. The typical RDSON resistance of these devices is
0.9
Ω and they are designed for approximately 1 A
output currents. Carrying the rated output current
continuously through the relay coil and the output
transistors of the FAN324x would cause excessive
power dissipation in the relay coil as well as in the
driver. It is therefore necessary to prevent the outputs to
be on continuously.
The maximum on-time of the FAN324x outputs is limited
by the protection logic circuit. Under no circumstances
should the outputs be on longer than the duration
specified by the tMAX parameter. Figure 27 demonstrates
operation of the output pulse width limiter of the device.
