8.4 Device Functional Modes

The following tables show the state of the output and the status of the part under various conditions.

Table 1. SVS-1 Truth Table

CONDITION OUTPUT STATUS
MR = Low SENSE1 < VITN RESET1 = Low Reset asserted
MR = Low SENSE1 > VITN RESET1 = Low Reset asserted
MR = High SENSE1 < VITN RESET1 = Low Reset asserted
MR = High SENSE1 > VITN RESET1 = High Reset released after delay

Table 2. SVS-2 Truth Table

CONDITION OUTPUT STATUS
SENSE2 < VITN RESET2 = Low Reset asserted
SENSE2 > VITN RESET2 = High Reset released after delay

Table 3. SVS-3 Truth Table

CONDITION OUTPUT STATUS
SENSE3 < VITN RESET3 = Low Reset asserted
SENSE3 > VITN RESET3 = High Reset released after delay

Table 4. SVS-4 Truth Table

CONDITION OUTPUT STATUS
SENSE4L < VITN SENSE4H > VITP RESET4 = Low Reset asserted
SENSE4L < VITN SENSE4H < VITP RESET4 = Low Reset asserted
SENSE4L > VITN SENSE4H > VITP RESET4 = Low Reset asserted
SENSE4L > VITN SENSE4H < VITP RESET4 = High Reset released after delay

Table 5. Watchdog Timer (WDT) Truth Table

CONDITION OUTPUT STATUS
WDO WDO RESET1 WDI PULSE INPUT
Low High Asserted Toggling WDO = low Remains in WDT time-out
Low High Asserted 610 ms after last WDI↑ or WDI↓ WDO = low Remains in WDT time-out
Low High Released Toggling WDO = low Remains in WDT time-out
Low High Released 610 ms after last WDI↑ or WDI↓ WDO = low Remains in WDT time-out
High Low Asserted Toggling WDO = high Normal operation
High Low Asserted 610 ms after last WDI↑ or WDI↓ WDO = high Normal operation
High Low Released Toggling WDO = high Normal operation
High Low Released 610 ms after last WDI↑ or WDI↓ WDO = low Enters WDT timeout
