Electrical characteristics

21/32

Note:

If the output voltage is lower than the min. value the VMON I²C bit is set to 1.

When VSEL=0: If VMON=0 then VoRX>85% of VoRX typical; If VMON=1 then VoRX<95% of

VoRX typical.

When VSEL=1: If VMON=0 then VoRX>84% of VoRX typical; If VMON=1 then VoRX<96% of

VoRX typical.

Note:

If the output current is lower than the min. threshold limit the IMON I²C bit is set to 1. if the

output current is higher than the max threshold limit the IMON I²C bit is set to 0.

Note:

If the 22 kHz tone parameters are lower or higher than the above limits the TMON I²C bit is

set to 1.
