In this case the electrical power dissipated in the sensitive layer must be limited and must not exceed 1mW for all values of RS. Heater Control To solve the application the sensor needs a certain temperature, the operation point. This temperature correlates with the heater resistance of the sensor module. The heater resistance and its TCR varies with production and the sensor temperature should be adjusted by applying a calibration step up front. In this calibration step the characteristic of the correlation of temperature and heater power is used. For iAQ applications the dependency for the operation temperature of ~300°C is 34mW @ 23°C ± 2°C. The measured heater resistance value with this applied conditions is the set-point which will be important for the further operation. Variation of ambient temperature may have an influence in the sensor temperature and its heater resistance. The chosen circuit shall be adjustable and should keep the heater resistance constant at the desired set-point. This can be solved by a basic PWM circuit shown in Figure 10.
