MLX90819

MLX90819 Relative Integrated Pressure Sensor Datasheet 1. Features and Benefits ▪ Fully integrated IC: MEMS, analog front end, 16 bit microcontroller, analog back end, voltage regulators, SENT driver ▪ Ratiometric Analog and SENT outputs ▪ Automotive temperature (-40°C to 150°C) ▪ Automotive qualified beyond AECQ100 ▪ Automotive diagnostic features (clamping levels, broken track diagnostics, multiple internal fault diagnostics) ▪ Glass pedestal for easy assembly and for back side exposed configuration for higher resistance to common automotive media ▪ High accuracy and robust EMC performance 3. Description The MLX90819 is an integrated relative pressure sensor delivering a ratiometric analog or digital (using the SENT protocol) signal. Use of an optimized architecture and a high density CMOS technology imparts the MLX90819 with best in class automotive EMC performance. A DSP based architecture using a 16bit microcontroller provides outstanding performance in terms of initial accuracy. The MLX90819 is mounted on a glass pedestal to ease the assembly of the die at the customers being the ideal solution for back side exposed pressure sensor applications requiring high accuracy, high EMC robustness, miniaturization and compliance to harsh automotive environments (See application note 90819 Pressure Sensor Assembly Guidelines).
