Stuck at Fault occurs when input OSC_IO input signal frequency drops below minimum frequency given in the Electrical Characteristics
table of this data sheet.
7.4.6 Fault Handling
If a fault situation occurs while in operation, the device acts accordingly to the fault being a global or a channel
fault. A global fault is a chip-wide fault situation and causes all PWM activity of the device to be shut down, and
will assert FAULT low. A global fault is a latching fault and clearing FAULT and restart operation requires
resetting the device by toggling RESET. Toggling RESET should never be allowed with excessive system
temperature, so it is advised to monitor RESET by a system microcontroller and only allow releasing RESET
(RESET high) if the OTW signal is cleared (high). A channel fault results in shutdown of the PWM activity of the
affected channel(s). Note that asserting RESET low forces the FAULT signal high, independent of faults being
present. TI recommends monitoring the OTW signal using the system micro controller and responding to an over
temperature warning signal by, that is, turning down the volume to prevent further heating of the device resulting
in device shutdown (OTE).

7.4.7 Device Reset
Asserting RESET low initiates the device ramp down. The output FETs go into a Hi-Z state after the ramp down
is complete. Output pull downs are active both in SE mode and BTL mode with RESET low.
In BTL modes, to accommodate bootstrap charging prior to switching start, asserting the reset input low enables
weak pulldown of the half-bridge outputs.
Asserting reset input low removes any fault information to be signaled on the FAULT output, that is, FAULT is
forced high. A rising-edge transition on reset input allows the device to resume operation after an overload fault.
To ensure thermal reliability, the rising edge of reset must occur no sooner than 4 ms after the falling edge of
FAULT.
