LEDset APPLICATIONS
Above 10 V and higher, the output current is maintained at
its maximum nominal value without turning off the ECG. In
this case, the accuracy features of the LEDset interface
can also be combined with infl exible light sensors with an
output range higher than 11 V. This capability to maintain
the Inom
max
from 10 to +12 V +10 % without turning off the
ECG output easily solves possible issues.
Furthermore, the current set confi guration also allows the
ECG to continuously supply its Inom
max
current if the Vset
input is left open (fl oating).
