LED-Short Diagnostics

As depicted in Configurable Outputs, the DIAG0 channel monitors the LED anode voltage of DRAIN0. When the DRAIN0 channel is turned on, DIAG0 compares the DRAIN0 voltage with the internal threshold for LED short detection, V(SC_th). When DRAIN0 is on and V(DIAG0) is continuously lower than V(SC_th) for tpd(deg_short), the device asserts an LED-short fault, sets the corresponding bit in the fault flag table, and pulls ERR low.

The device does not turn off the channel automatically in LED-short state. Once device detects a short fault, it latches the fault state in the DIAGn_SHORT fault register. The fault register value only recovers to normal when LED fault disappears and the fault status is read back. Cycling Gx on and off does not clear the fault.
