Manufacturer:NXP Description:A measurement is initiated when the supply is applied pro- vided the control input pin 7 is low Once a measurement is commenced pin 7 is latched low and the ramp capacitor on pin 12 begins to charge After 25 ms when switch-on tran- sients have subsided a constant current is applied to the thermo-resistive probe The value of probe current which is supplied by an external PNP transistor is set by an external resistor across an internally generated 21V reference The lamp current is applied at the start of probe current 35 ms after switch-on the voltage across the probe is sam- pled and held on external capacitor C1 (leakage current at pin 1 less than 1 nA) After a further 1 5 seconds the differ- ence between the present probe voltage and the initial probe voltage is measured multiplied by 3 and compared with a reference voltage of 850 mV (externally adjustable via pin 16) If the amplified voltage difference is less than the reference voltage the lamp is switched off otherwise the lamp commences flashing at 1 Hz to 2 Hz 10 ms later the measurement latch operates to store the result and af- ter a further 8 ms the probe current is switched off A second measurement can only be initiated by interrupting the supply An external CR can be arranged on pin 7 to prevent a second measurement attempt for 1 minute The measurement condition stored in the latch will control the lamp |
