While in the Fault state, a number of parameters are continuously monitored.

For the following parameters, if a fault condition is detected, the device stays in FAULT state until and unless the fault condition is removed and then the device transitions to DIAGNOSTIC state:

• The VCC overvoltage check as described in Normal State Diagnostics.
• The VCC undervoltage check as described in Normal State Diagnostics.
• The VREG overvoltage check as described in Normal State Diagnostics.
• The thermal shutdown check as described in Normal State Diagnostics.

For the following parameters, if a fault condition is detected, the device is transferred to the DISABLED state and a recovery is attempted (see DISABLED State):

• The Critical registers redundancy check as described in Normal State Diagnostics.
• The TM0 state check as described in the Normal State Diagnostics.
• The TOUT state check as described in the Normal State Diagnostics.
• The AGC_EN toggle check as described in Normal State Diagnostics.

For all other faults, the device attempts recovery by transitioning to DIAGNOSTIC state while the OUTx pins remain in FAULT signaling state.
