1300 DegC Thermocouple Interface IC alerts if sensor fails in automotives

The temperature sensor interface IC MLX90327 from Melexis has built-in diagnostic capabilities to find if the temperature sensor is malfunctioning. This IC is specifically designed for automotive applications where temperature of engine need to be monitored using thermostat or a thermocouple. By having its own operating temperature capability in the range of -40°C to 150°C, this IC supports thermocouples which can measure temperature upto 1300°C.

The MLX90327 feature digital SENT interface for advanced powertrain electronic control units (ECUs). PWM output is available for general-purpose automotive and non-automotive applications both from Pt-sensors and thermocouples. MLX90327 offers protection against overvoltage and electro-static discharge (ESD) events ensure longevity.

Due to its high temperature measurement capabilities, MLX90327 use in exhaust gas recirculation (EGR) system helps to have more energy efficient turbo chargers and better cleaning treatments of exhaust gases, diesel particle filter and the diesel oxidation catalyst. MLX90327 can also be used in braking systems of trucks for measuring elevated temperature. MLX90327 suggested for industrial process control systems where such temperatures need to be measured and monitored.
