The more the temperature is exceeded, the greater the reduction of output current.  Thermistor input is required for driver operation. Driver will limit maximum current output to less than 2A if no thermistor connection is detected. o The LED thermal protection function can be bypassed by placing a 2KΩ-10KΩ resistor across J5. Note that in doing so, the LVHC driver will not be able to detect excessive high-temperature LED operation.  The below graph shows how the LVHC driver limits maximum current output to protect the LED. Note that using a different thermistor from the one specified will alter its behavior during high-temperature operation (per the above graph). ©2021 Cuvee Systems. All rights reserved.
