Discrete Infrared Thermopile Detectors Solid State Sensor Small Size MLX90247

MLX90247 Discrete Infrared Thermopile Detectors

Product Introduction :

The MLX90247 family sensors are thermopile sensors IC which detects very small amounts of heat radiation. The sensors consist of a

membrane with a thermopile on top of it.

The hot junctions of the thermopile are positioned near the center of the membrane and the cold junctions above the bulk silicon edge.

Due to the low thermal conductivity of the membrane, absorbed heat will cause the temperature to increase more at the center of the

membrane than at the edge above the bulk. This temperature difference is converted to an electric potential by the thermo-electric effect

in the thermopile junctions. No supply voltage is needed.

The MLX90247DSG sensor IC is integrated together with a PTC thermistor. The thermopile sensor is grounded at the middle point,

so that the output common-mode voltage is at ground potential. Using grounded thermopile sensor gives improved EMC susceptibility

in some applications.

The MLX90247DSE sensor IC is packaged together with a 100k NTC chip thermistor. The sensor and thermistor can be used independent

of each other if desired, as the thermopile potential is floating. This type of thermistor has better sensitivity than the PTC types, but must

be used in smaller ambient ranges. Typical applications are ear thermometers or other medical equipment.

The MLX90247DSA sensor IC is integrated together with a PTC thermistor. The sensor and thermistor can be used independent of each

other if desired, as the thermopile potential is floating
