Transceiver

Output drivers (C/QO and L+) are protected against short-circuit or overcurrent by means of

two different functions.

One is the current limiting function: output current is linearly limited to ILIMQ/L.

The cutoff protection, on the other side, is intended to turn off the drivers when the output

current exceeds a (programmable for the C/QO driver) threshold (ICOL/I). When the current

reaches the (programmed) cutoff value the channel output driver is turned off after

a programmable delay (tdcoq/l). The channel output driver automatically restarts again after

a programmable delay time (trcoq/l). See Figure 38.
