FUNCTIONAL DEVICE OPERATION
OPERATIONAL MODES
OPERATIONAL MODES
The 10XS3435 has four operating modes: Sleep, Normal,
Fail-Safe and Fault. Table 6 and Figure 12 summarize details
contained in succeeding paragraphs.
The Figure 11 describes an internal signal called IN_ON[x]
depending on IN[x] input.

Figure 11. IN_ON[x] internal signal
The 10XS3435 transits to operating modes according to
the following signals:
• wake-up = RST or WAKE or IN_ON[0] or IN_ON[1] or
IN_ON[2] or IN_ON[3],
• fail = (VDD Failure and VDD_FAIL_en) or (Watchdog
time-out and FSI input not shorted to ground),
• fault = OC[0:3] or OT[0:3] or SC[0:3] or UV or (OV and
OV_dis).

x = Don’t care.
x x Device is in Sleep mode. All
outputs are OFF.
0 0 Device is currently in Normal
mode. Watchdog is active if
enabled.
1 0 Device is currently in Fail-safe
mode due to Watchdog time-
out or VDD Failure conditions.
The output states are defined
with the RFS resistor
connected to FSI.
X 1 Device is currently in fault
mode. The faulted output(s) is
(are) OFF. The safe autoretry
circuitry is active to turn-on
again the output(s).
