Product details
Overview
MLX90817LXE-DBG-003-SP from Melexis is an automotive-grade absolute pressure sensor IC with integrated MEMS sensing element, 16-bit microcontroller, analog front end, and ratiometric analog output. It delivers 0.2–5.5 bar full-scale pressure measurement with ±53 mbar total accuracy over –40°C to +150°C, factory calibrated for manifold and turbo manifold air pressure applications in engine control units.
For engineers reviewing the MLX90817LXE-DBG-003-SP datasheet, pinout, applications, or equivalent options, this page provides verified functional architecture, diagnostic capabilities, clamping behavior, filter programmability, and automotive EMC performance data directly traceable to Melexis REV 010 documentation.
Technical Context
The MLX90817LXE-DBG-003-SP implements a DSP-based signal chain: piezoresistive Wheatstone bridge feeds into a chopper-stabilized instrumentation amplifier (programmable gain 4.49–10.6 V/V), followed by differential ADC (16-bit, ±VDDA/2 range) and real-time temperature-compensated linearization using EEPROM-stored coefficients (O0–O3, G0–G3, L0–L1). Its architecture supports both small-signal filtering (SSF) and programmable first-order low-pass filtering (PFLT = 0–9).
It integrates automotive diagnostics including broken-track detection on supply/ground lines, overvoltage/undervoltage monitoring, clamping level programming (0–12.5% and 50–100% Vdd), and internal fault reporting via analog rail-driving behavior. The device operates from 4.5–5.5 V supply with 8.5–10 mA current draw and features overvoltage protection up to +18 V and reverse voltage tolerance down to –14 V.

Applications
| Manifold Absolute Pressure (MAP) Sensing | Turbo Manifold Air Pressure |
|---|---|
Use Scenario: Real-time monitoring of intake manifold pressure in gasoline direct injection engines for fuel metering and ignition timing control. IC Role / Device Role / Timing Role: Primary absolute pressure transducer delivering ratiometric analog output synchronized to ECU sampling clock (200 µs update rate). Use Value: ±53 mbar accuracy across –40°C to +150°C ensures consistent air-mass calculation despite thermal cycling and vibration stress. | Use Scenario: Feedback sensing of compressed air downstream of turbocharger for boost control and wastegate actuation. IC Role / Device Role / Timing Role: High-bandwidth pressure node with 0.93 ms response time (PFLT=0) enabling closed-loop boost regulation at >100 Hz. Use Value: 15 bar burst rating and AEC-Q100 qualification support reliable operation under transient overboost conditions. |
| LPG/CNG Injector Monitoring | Engine Control Unit (ECU) Safety Diagnostics |
Use Scenario: Pressure verification upstream of gaseous fuel injectors to confirm proper regulator function and detect leaks or blockages. IC Role / Device Role / Timing Role: Absolute reference sensor interfacing directly with ECU analog input channel - no external signal conditioning required. Use Value: Factory-calibrated 0.2–5.5 bar range matches typical LPG/CNG rail pressures; ratiometric output rejects supply ripple common in vehicle electrical systems. | Use Scenario: Integrated safety monitor providing real-time fault status (open-circuit, short-to-battery, short-to-ground) to ISO 26262 ASIL-B compliant ECUs. IC Role / Device Role / Timing Role: Diagnostic subsystem component - asserts low/high fault bands on analog output when supply or ground disconnects occur. Use Value: Broken-track diagnostics reduce need for external supervision circuits; clamping levels programmable to match ECU ADC thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700AP | 700 kPa range (0–7 bar), 0.2–1.0 V output, no integrated MCU or diagnostics | Requires external compensation and signal conditioning; lacks automotive diagnostics and programmable filters | Lower-cost option where full AEC-Q100 qualification and self-diagnostics are not required |
| SSM2200-5.5B | 0.2–5.5 bar range, 0.5–4.5 V output, but no EEPROM programmability or clamping configuration | Fixed transfer curve and diagnostic thresholds - cannot adapt to custom ECU ADC ranges or safety logic | Suitable for non-safety-critical applications needing basic ratiometric output without field reconfiguration |
Compared with MPX5700AP and SSM2200-5.5B, the MLX90817LXE-DBG-003-SP provides higher integration (on-chip DSP, EEPROM, diagnostics), wider temperature range (–40°C to +150°C vs. –40°C to +125°C), and design flexibility through programmable clamping and filtering - critical for ASIL-B-compliant engine management systems.

FAQ
What is the pressure range and output behavior of the MLX90817LXE-DBG-003-SP?
The MLX90817LXE-DBG-003-SP is factory configured for 0.2–5.5 bar absolute pressure measurement with a ratiometric analog output spanning 0.5 V to 4.5 V. This output scales linearly with supply voltage (4.5–5.5 V); at 5 V supply, 0.2 bar yields ~0.5 V and 5.5 bar yields ~4.5 V. The transfer curve is stored in on-chip EEPROM and supports reprogramming for custom calibration.
Does the MLX90817LXE-DBG-003-SP support diagnostic functions required for automotive safety systems?
Yes, the MLX90817LXE-DBG-003-SP includes multiple automotive-grade diagnostics: broken-track detection on supply and ground lines, overvoltage/undervoltage monitoring, overpressure/underpressure flags, and configurable clamping levels. Faults drive the analog output to predefined low or high fault bands, enabling ECU-level safety monitoring without external circuitry - supporting ASIL-B system designs.
Can the MLX90817LXE-DBG-003-SP be reprogrammed in-system for different pressure ranges or output curves?
Yes, the MLX90817LXE-DBG-003-SP supports full in-system reprogramming via its dedicated communication mode (entered by applying 6.2–7.8 V to VDD). All EEPROM parameters - including pressure transfer curve coefficients (O0–O3, G0–G3), clamping levels, filter settings (PFLT, SSF), and diagnostic thresholds - can be updated using Melexis-provided tools and protocols.
What is the response time of the MLX90817LXE-DBG-003-SP under default filter settings?
With default filter settings (PFLT = 0 and SSF disabled), the MLX90817LXE-DBG-003-SP achieves a 90% step response time of 0.93 ms. This value is confirmed in Table 13 of the datasheet and applies to pressure steps within the 0.2–5.5 bar range. Increasing PFLT extends response time up to 203.8 ms (PFLT = 9) for enhanced noise rejection.
Is the MLX90817LXE-DBG-003-SP qualified for automotive use and what package does it use?
Yes, the MLX90817LXE-DBG-003-SP is AEC-Q100 Grade 0 qualified (–40°C to +150°C) and assembled in a 4×5 mm DFN14 package with wettable flanks. The package supports automated optical inspection and is rated for burst pressure up to 15 bar at room temperature - meeting stringent requirements for engine bay deployment.
