What differentiates the MAX3191x family from the competition are power draw/heat buildup, and robust CRC communications for the serializers. As an example, the MAX31913 draws 60% less power from the field voltage than the discrete solution and up to 25% less than competing ICs. The quiescent current of the MAX31913 is 80% less than that of the IC competition. The two images shown here are actual thermal images for the MAX31913 and a competitors IC with all 8 field inputs set to 24 V. The ambient temperature was 25°C, current limit programmed to 2.4 mA for a period of 120 minutes.
