If one or more channels of the device are in PLAY state the device may need to take protective actions and shutdown one or more audio channels. The output FETs of the affected channels is turned off and the output pins are high impedance. The reported state for affected channels is PROTECTIVE SHUTDOWN

Possible reasons for individual channels to enter this state are:

• Over Current Shutdown
• Load Current Fault
• DC fault
• Channel over temperature shutdown (OTSD(i))

Possible reason for all channels to enter this state is:

• Global over temperature shutdown (OTSD)

The following registers hold all information necessary to identify the reason for the device being in this state:

• Temperature (OTSD) and Clock Sync Fault Status Register
• Channel Over Current and DC Detection Fault Memory Register
• Channel Load Current Fault Memory Register
