14.2.41. Register REMOTE_TEMPERATURE
The controller allows for the connection of an external temperature sensor (see
section 7.4.4
for more
information).
This register contains the measured temperature, expressed as a signed sixteen bits integer, with a
resolution of 0.1 °C. Given the register value, the corresponding actual temperature for the remote
sensor can be calculated as follows:
RemoteTemperature [°C] = value(REMOTE_TEMPERATURE) * 0.1
In case the external temperature sensor is not connected, the value in the register is undefined.
14.3.42. Register BOARD_TEMPERATURE[0:3]
The controller integrates four temperature sensors. There is a temperature sensor for every couple of
power stages.
BOARD_TEMPERATURE0
: average temperature of LD1 and LD2 power stages
BOARD_TEMPERATURE1
: average temperature of LD3 and LD4 power stages
BOARD_TEMPERATURE2
: average temperature of LD5 and LD6 power stages
BOARD_TEMPERATURE3
: average temperature of LD7 and LD8 power stages
These registers contain the measured temperatures, expressed as signed sixteen bits integers, with a
resolution of 0.1 °C. Given a register value, the corresponding actual temperature for a couple of
power stages can be calculated as follows:
BoardTemperature[x] [°C] = value(BOARD_TEMPERATURE[x]) * 0.1
The average heatsink temperature may be estimated by averaging the temperatures measured by the
four temperature sensors.
14.2.43. Register SUPPLY_VOLTAGE
The controller is capable of measuring the actual supply voltage for the power stages.
This register contains the measured supply voltage, expressed as an unsigned sixteen bits integer,
with a resolution of 0.1 V. Given the register value, the corresponding actual supply voltage for the
power stages can be calculated as follows:
SupplyVoltage [V] = value(SUPPLY_VOLTAGE) * 0.1
The measured value drops to zero if the supply for the power stages is removed.
14.2.44. Registers MEASURED_CURRENT[0:7]
The controller is capable of measuring the actual output currents for the eight light outputs.
MEASURED_CURRENT0
: measured current for light output LD1
MEASURED_CURRENT1
: measured current for light output LD2
MEASURED_CURRENT2
: measured current for light output LD3
MEASURED_CURRENT3
: measured current for light output LD4
MEASURED_CURRENT4
: measured current for light output LD5
MEASURED_CURRENT5
: measured current for light output LD6
