Fault Flag Indication

At normal mode, the FAULT pin is pulled to

high by pull-up resistor. When the short/open

LED protection, OVP protection, inductor/diode

short protection, or thermal shutdown protection

condition is detected, the FAULT pin is pulled to

GND which provides a fault state to the master

system. Note that disabling the unused

channels by connecting CTLX to GND will not

change the FAULT normal condition.
