Table 4. General Fault Register Format
TWARN: The TWARN bit is set to ‘1’ when the temperature warning threshold is reached.
TSHDN: The TSHDN is set to ‘1’ when the temperature shutdown threshold is reached.
DUMP: The DUMP bit is set to ‘1’ when the V
Set the appropriate mask bit in the GMASK register to detect the general faults. See Table 8.
Table 5. Left-Channel Fault Register Format
SVDDL: The SVDDL bit is set to ‘1’ when a short to V
SGNDL: The SGNDL bit is set to ‘1’ when a short to GND is detected on the left channel.
LIMITL: The LIMITL bit is set to ‘1’ when the current-limit threshold is tripped for left output.
OFFSETL: The OFFSETL bit is set to ‘1’ when excessive offset is detected on the left-channel output.
OPENL: The OPENL bit is set to ‘1’ when an open load is detected on the left channel.
Set the appropriate mask bit in the LMASK register to detect the faults on the left channel. See Table 9.
When any bit of the LFAULT register is high, the FLAG output is low.
Table 6. Right-Channel Fault Register Format
SVDDR: The SVDDR bit is set to ‘1’ when a short to V
SGNDR: The SGNDR bit is set to ‘1’ when a short to GND is detected on the right channel.
LIMITR: The LIMITR bit is set to ‘1’ when the current-limit threshold is tripped for right output.
OFFSETR: The OFFSETR bit is set to ‘1’ when excessive offset is detected on the right-channel output.
OPENR: The OPENR bit is set to ‘1’ when an open load is detected on the right channel.
Set the appropriate mask bit in the RMASK register to detect the faults on the right channel. See Table 10.
When any bit of the RFAULT register is high, the FLAG output is pulled low.
