Product details
Overview
MLX90820LUF-EBA-000-WB from Melexis is an automotive-grade absolute pressure sensor IC delivering ratiometric analog and SENT digital outputs, featuring a 16-bit microcontroller-based DSP architecture, ±0.2%FSO non-linearity (10–35 bar range), -40°C to 150°C operating temperature, and integrated diagnostics for clamping, broken-track, and internal fault detection - deployed in HVAC refrigeration and industrial oil-filled pressure modules.
For engineers reviewing the MLX90820LUF-EBA-000-WB datasheet, pinout, applications, or equivalent options, this page provides verified technical context, bond pad mapping, pressure accuracy specs, diagnostic configuration details, and validated alternatives for mid-pressure sensing in harsh environments.
Technical Context
The MLX90820LUF-EBA-000-WB integrates a piezoresistive silicon diaphragm with on-chip analog front-end, 16-bit microcontroller, DSP-based temperature compensation, and dual-output capability (analog ratiometric and SENT J2716-compliant). Its architecture delivers <1 ms analog response time and 3–4 frame SENT response under default filter settings.
It implements programmable clamping (8-bit low / 9-bit high resolution), EEPROM-protected calibration data, and robust EMC performance enabled by high-density CMOS process and optimized layout - all within a bare die format delivered on sawn wafer with electronic wafer map (WB packing).

FAQ
What is the pressure range supported by the MLX90820LUF-EBA-000-WB?
The MLX90820LUF-EBA-000-WB is factory-configured for a 10–35 bar absolute pressure range (EBA-000 option), with proof pressure rated at 70 bar and burst pressure at 105 bar at room temperature. This range targets mid-pressure applications including refrigerant monitoring and industrial hydraulic feedback.
Does the MLX90820LUF-EBA-000-WB support both analog and digital outputs simultaneously?
No - the MLX90820LUF-EBA-000-WB supports either analog ratiometric output (via OUT pin) or SENT digital output (via TX pin), but not both concurrently. The output mode is selected during system design and wiring; both share the same VDD and GND connections and internal calibration data.
How is diagnostic functionality implemented in the MLX90820LUF-EBA-000-WB?
The MLX90820LUF-EBA-000-WB implements diagnostics including clamping level detection, broken-track monitoring, and internal fault flags (over/under-pressure, over/under-voltage). These are programmable via EEPROM and reported through output signal behavior - e.g., driving OUT or TX to rail states upon detected faults.
What packaging form does the MLX90820LUF-EBA-000-WB ship in?
The MLX90820LUF-EBA-000-WB ships as a bare die on fully tested wafers (UF package), with "WB" denoting wafer box packing. Each wafer includes an electronic wafer map to identify functional dies, and the die measures 2.555 mm × 2.555 mm ±0.05 mm excluding scribe lanes.
Is the MLX90820LUF-EBA-000-WB qualified for automotive applications?
Yes - the MLX90820LUF-EBA-000-WB carries L-temperature qualification (-40°C to +150°C), meets automotive EMC requirements, and includes diagnostic features aligned with ASIL-B readiness. It is widely deployed in automotive HVAC and air conditioning systems requiring robust, calibrated pressure feedback.
