7.4.3 Fault Mode

The TLC6C5716-Q1 has full diagnostics features. The device can detect faults and latch the faults into registers. For device faults such as IREF resistor open or short, the device enters a self-protection state, in which it reports the faults and sets the output current to a default value. For the overtemperature fault, the device turns off the output channels and latches the fault into the SID register. Except for these two faults, for all other faults including LED faults, the device only detects and reports the faults, but does not take actions to handle the faults, and the channels keep their configured status. Users must read out faults and decide how to handle the faults.
