Product details
Overview
MLX90819LUF-EBB-000-WB from Melexis is a fully integrated relative pressure sensor die delivering ratiometric analog or SENT digital output, designed for 30–50 bar mid-pressure automotive applications including engine oil and fuel line monitoring. It features a piezoresistive MEMS sensing element, 16-bit microcontroller-based DSP compensation, glass pedestal mounting for back-side exposure, and operates across −40°C to +150°C.
For engineers reviewing the MLX90819LUF-EBB-000-WB datasheet, pinout, applications, or equivalent options, this page provides verified functional roles, validated bond pad mapping, calibrated pressure accuracy (±0.2% FSO non-linearity), diagnostic capabilities (clamping, broken track, over/under-pressure), and wafer-level packaging details for bare-die integration.
Technical Context
The MLX90819LUF-EBB-000-WB implements a silicon piezoresistive diaphragm with on-chip temperature sensing, 16-bit ADC, and DSP-based real-time gain/offset compensation across temperature. Its architecture supports programmable filter settings (SSF=1, PFLT=0 default), pressure linearization, and clamping thresholds with 8-bit (low) and 9-bit (high) resolution.
It delivers dual-output capability: analog output (ratiometric, 0–5 V, ±0.2% VDD ratiometricity error) and SENT-compliant digital output (SAE J2716 Jan 2010), both with independent diagnostics logic, reverse polarity protection (−14 V), and overvoltage tolerance (+18 V). The die integrates voltage regulators, EEPROM for configuration storage, and active broken-track detection.
Key Specifications

FAQ
What is the pressure range calibrated for MLX90819LUF-EBB-000-WB?
The MLX90819LUF-EBB-000-WB is factory-calibrated for a 30–50 bar full-scale pressure range (Option Code EBB), with non-linearity error specified at ±0.2% FSO at room temperature using two-point calibration (30 bar and 50 bar). This range is optimized for high-pressure automotive oil and fuel systems where precision and burst tolerance are critical. MLX90819LUF-EBB-000-WB does not support reprogramming to alternate spans in the field.
Does MLX90819LUF-EBB-000-WB support both analog and SENT outputs simultaneously?
No-MLX90819LUF-EBB-000-WB supports either analog output (via OUT pin) or SENT output (via TX pin), but not both concurrently. The output mode is selected at power-up by internal configuration stored in EEPROM; users must choose one interface per application design. Both outputs share the same pressure measurement path and compensation algorithms, ensuring consistent accuracy regardless of selected mode. MLX90819LUF-EBB-000-WB requires no external mode-select circuitry.
What packaging form does MLX90819LUF-EBB-000-WB ship in?
MLX90819LUF-EBB-000-WB ships as a bare die on fully tested wafers in wafer box (WB) packaging, with "UF" indicating sawn wafer on foil. Each wafer includes an electronic wafer map identifying functional dies. The die measures 2.555 mm × 2.555 mm (±0.05 mm) and mounts on a glass pedestal for back-side pressure exposure-no leadframe, molding compound, or standard IC package is included. MLX90819LUF-EBB-000-WB is intended for die-bonding into custom sensor housings.
How are diagnostics configured on MLX90819LUF-EBB-000-WB?
Diagnostics-including clamping levels, broken-track detection, over/under-pressure flags, and supply monitoring-are configured via EEPROM programming using Melexis' proprietary calibration tools during wafer probe or final test. Default settings are preloaded; users can adjust clamping thresholds (8-bit low / 9-bit high resolution), enable/disable specific diagnostics, and set filter parameters (SSF, PFLT). MLX90819LUF-EBB-000-WB does not support runtime reconfiguration via SENT or analog interface.
Is MLX90819LUF-EBB-000-WB qualified to AEC-Q100?
Yes-MLX90819LUF-EBB-000-WB is qualified beyond AEC-Q100 Grade 0 (−40°C to +150°C), with additional stress testing including extended temperature cycling, high-acceleration mechanical shock, and rigorous EMC validation per ISO 11452 and CISPR 25. Its qualification covers the full die, glass pedestal, and bond pad structure. MLX90819LUF-EBB-000-WB is approved for safety-critical powertrain applications including engine oil and transmission pressure monitoring.
