Product details

Overview

MLX90818LXE-BBG-017-RE from Melexis is an automotive-grade absolute pressure sensor with integrated 16-bit microcontroller, SENT digital output, and on-chip NTC temperature interface. It delivers ±0.5% FS pressure accuracy over –40°C to 150°C, 0.1–4 bar full-scale range, and ±1°C compensated NTC temperature data - deployed in turbo manifold air pressure monitoring systems requiring high reliability under harsh thermal and EMC conditions.

For engineers reviewing the MLX90818LXE-BBG-017-RE datasheet, pinout, applications, or equivalent options, this page provides verified technical context, SENT protocol timing constraints, NTC linearization architecture, pressure transfer curve parameters (P1=0.1 bar, P2=4 bar, O1=193 LSB, O2=3896 LSB), and diagnostic configuration options for automotive ECU integration.

Technical Context

The MLX90818LXE-BBG-017-RE implements a piezoresistive MEMS sensing element with Wheatstone bridge output, amplified by a programmable analog front end (Gst1=4.49–10.6 V/V, Gst2=–1.25 or –3.5 V/V, Gst3=1.6–6.4 V/V) and digitized by a 16-bit differential ADC referenced to VDDA/2. Its DSP-based compensation engine applies third-order temperature-dependent gain/offset correction and optional pressure linearization using EEPROM-stored coefficients (O0–O3, G0–G3, L0–L1).

Digital functionality centers on a 16-bit microcontroller executing SENT J2716-compliant frame generation (fast channel for pressure, slow channel for NTC temperature), dual-stage filtering (PFLT programmable 0–9, SSF enable/disable), and comprehensive diagnostics including overvoltage, reverse voltage, broken-wire, and clamping detection - all configurable via EEPROM programming through the supply line.

Key Specifications

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute pressure sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90818LXE-BBG-016-RE	Same package and architecture; 0.1–3 bar range, identical NTC interface and SENT format.	Optimized for naturally aspirated engines with lower peak boost; reduced full-scale pressure headroom.	Select when maximum pressure does not exceed 3 bar and cost-sensitive calibration is prioritized.
MPX5700AC6U	Analog output (ratiometric 0.2–4.8 V), no integrated microcontroller or SENT; requires external ADC and signal conditioning.	Lacks on-chip temperature compensation, diagnostics, and programmable filtering - increases system design effort.	Choose only if legacy analog interface is mandated and ECU has spare ADC resources and processing bandwidth.

Compared with MLX90818LXE-BBG-016-RE, the MLX90818LXE-BBG-017-RE extends full-scale pressure range by 33% while retaining identical accuracy, NTC performance, and diagnostic features; versus MPX5700AC6U, it replaces three external components (ADC, regulator, microcontroller) with single-chip SENT output and embedded calibration - reducing PCB area by >40% and qualification effort.

What diagnostic functions are built into the MLX90818LXE-BBG-017-RE?

The MLX90818LXE-BBG-017-RE integrates overvoltage (up to 18 V), reverse voltage (down to –18 V), supply undervoltage, open-circuit NTC, and pressure out-of-range diagnostics. Diagnostic status is reported via SENT message bits and can trigger configurable clamping or error frames - enabling ASIL-B–compliant fault handling without external supervision circuitry.

Can the MLX90818LXE-BBG-017-RE be reprogrammed in-system?

Yes, the MLX90818LXE-BBG-017-RE supports in-system EEPROM programming through its supply pin (Vdd) using Melexis' proprietary communication protocol.
