Virtually any small signal switching diode with dUF/dT
temperature sensor is available on J2, Pin6. If used, the on-board temperature sensor D2 must be switched off.
This is achieved by removing Jumper JMP1 (set by default). The following schematic shows the connection of an
external temperature sensor:
Any programming of the circuit is accomplished via the calibration pin CALIB. It is accessible at connector J2,
Pin 3. A jumper that is set by default between CALIB and GND (to protect the CALIB pin from voltages that could
result in faulty programming) has to be removed before programming.
Supply (VS) and GND have to be applied at this connector too as shown below in figure 4. Only these
three wires are necessary for programming. For details about the calibration interface and procedure please refer
to the MLX10801 IC specification.
Note: Do not use VBAT at connector J1 (Pin3) to supply the board in programming mode! Due to the
additional voltage drop caused by the reverse polarity diode D1, the voltage levels of the multilevel CALIB
interface may shift in a way that proper programming can not be guaranteed anymore (however it will
function properly in most cases).
