FAIL-SAFE INPUT (FSI)
and ground determines the state of the outputs after a
Watchdog timeout occurs. Depending on the resistance
value, either all outputs are OFF or the output HSO only is
ON. If the FSI pin is left to float up to a logic [1] level, then the
outputs HS0 and HS2 will turn ON when in the Fail-Safe
state. When the FSI pin is connected to GND, the Watchdog
circuit and Fail-Safe operation are disabled. This pin
incorporates an active internal pullup current source.
