MLX90819

Relative Integrated Pressure Sensor Datasheet

1. Features and Benefits

3. Description

The MLX90819 is an integrated relative pressure sensor

delivering a ratiometric analog or digital (using the SENT

protocol) signal.

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

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 16bit microcontroller provides

outstanding performance in terms of initial accuracy.

Automotive diagnostic features (clamping

levels, broken track diagnostics, multiple

internal fault diagnostics)

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).

Glass pedestal for easy assembly and for

back side exposed configuration for higher

resistance to common automotive media
