Product details
Overview
MLX90820LUF-EBB-000-WB from Melexis is an automotive-grade absolute pressure sensor IC delivering ratiometric analog and SENT digital outputs, with 30–50 bar full-scale range, ±0.2% FSO non-linearity at room temperature, and operation from −40°C to +150°C. It integrates MEMS sensing element, 16-bit microcontroller, analog front-end/back-end, voltage regulators, and SENT driver on a single die for mid-pressure industrial and HVAC applications.
For engineers reviewing the MLX90820LUF-EBB-000-WB datasheet, pinout, applications, or equivalent options, key selection factors include its programmable clamping diagnostics, built-in EEPROM protection, burst pressure rating of 140 bar, and wafer-level delivery with electronic map for die-level integration into oil-filled modules.
Technical Context
The MLX90820LUF-EBB-000-WB implements a piezoresistive silicon diaphragm with on-chip temperature sensing, followed by a 12-bit DAC-based analog output path and a SAE J2716-compliant SENT transmitter. Its DSP-based compensation uses factory-calibrated coefficients stored in EEPROM to correct offset, gain, and linearity across temperature.
Diagnostics include broken-track detection, over/under-voltage monitoring, over/under-pressure flags, and programmable clamping thresholds (8-bit low / 9-bit high resolution). The device supports both analog mode (OUT pin) and SENT mode (TX pin), with dedicated bond pads and no shared functionality between output paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Pressure Range | 30–50 bar full-scale span, calibrated for EBB option code; enables precise monitoring in high-mid pressure hydraulic and refrigerant systems. |
| Accuracy (Non-Linearity) | ±0.2% FSO at room temperature (30/50 bar calibration points); ensures stable measurement without external linearization in embedded control loops. |
| Output Interfaces | Ratiometric analog (0–5 V, 12-bit effective) and SENT digital (SAE J2716 Jan 2010 compliant); supports dual-path redundancy or system-level flexibility. |
| Operating Temperature | −40°C to +150°C ambient; qualified for under-hood automotive and industrial environments without derating. |
| Burst Pressure | 140 bar at room temperature; provides mechanical safety margin for transient overpressure events in oil-filled modules. |
| Supply Current | 7–8 mA typical at 5 V; enables low-power operation in battery-backed or energy-constrained sensor nodes. |
| Response Time | 1 ms (analog), 3–4 SENT frames (≈3–4 µs per frame with pause pulse); suitable for real-time closed-loop pressure regulation. |
Pinout & Package

Applications
| Refrigeration System Monitoring | HVAC Compressor Control |
|---|---|
|
Use Scenario: Real-time suction/discharge pressure monitoring in variable-speed R410A/R32 refrigeration units to prevent compressor stall and optimize expansion valve timing. IC Role / Device Role / Timing Role: Absolute pressure transducer providing SENT-synchronized readings every 3–4 frames for closed-loop PID control at 100 Hz update rate. Use Value: Enables 0.2% FSO accuracy over −40°C to +150°C without recalibration, reducing field failure rates in outdoor condensing units. |
Use Scenario: High-temperature pressure feedback in rooftop HVAC compressors operating continuously at 130°C ambient with oil-lubricated refrigerant circulation. IC Role / Device Role / Timing Role: Analog ratiometric output (OUT pin) feeds into microcontroller ADC for fast-response overload protection with <1 ms latency. Use Value: Burst pressure rating of 140 bar prevents catastrophic rupture during refrigerant slug events, extending service life beyond 15 years. |
| Industrial Hydraulic Load Sensing | Oil-Filled Pressure Transmitter Module |
|
Use Scenario: Embedded pressure feedback in mobile hydraulic valves for excavator boom control, where vibration and thermal cycling exceed 10⁶ cycles. IC Role / Device Role / Timing Role: Dual-output capability allows SENT for CAN bus telemetry and analog for local safety cutoff - independent signal paths enhance functional safety. Use Value: Built-in broken-track diagnostics detect open-circuit faults in harnesses before actuator misfire, meeting ASIL-B diagnostic coverage requirements. |
Use Scenario: Core sensing element in OEM-designed oil-filled stainless-steel pressure transmitters for chemical process instrumentation. IC Role / Device Role / Timing Role: Bare-die integration (UF package) directly onto ceramic substrate with silicone oil fill; eliminates wire-bond fatigue and interface delamination. Use Value: Oil charge immunity and −40°C to +150°C operation ensure metrological stability in aggressive media (e.g., glycol, mineral oil, synthetic esters). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar absolute pressure sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MPX5700系列 (NXP) | 70 bar analog-only output; no SENT interface; ±2% FSO accuracy; SO-8 packaged IC requiring external signal conditioning. | Lacks integrated diagnostics, EEPROM, and digital output - requires companion MCU for SENT conversion and fault handling. | Choose MPX5700 only if analog-only interface suffices and board space permits discrete signal chain design. |
| TDK InvenSense ICP-10125 | I²C digital output only; 1–2 bar range; ±0.5% FSO; MEMS + ASIC in 2.0 × 2.0 mm LGA; no oil compatibility or automotive temp rating. | Designed for consumer-grade barometric sensing, not industrial oil-filled modules or high-temp hydraulic use. | Select ICP-10125 only for low-pressure, non-oil, non-automotive applications where I²C interface and small footprint are primary drivers. |
Compared with MPX5700 and ICP-10125, the MLX90820LUF-EBB-000-WB uniquely combines 30–50 bar range, SENT+analog dual output, automotive-grade diagnostics, and bare-die oil compatibility - enabling direct integration into high-reliability, high-EMC industrial pressure modules without external components.

FAQ
What pressure range does the MLX90820LUF-EBB-000-WB support?
The MLX90820LUF-EBB-000-WB is factory-programmed for a 30–50 bar absolute pressure range (EBB option code), with calibration performed at 30 bar and 50 bar endpoints. Its proof pressure is 105 bar and burst pressure is 140 bar at room temperature - making it suitable for high-stress hydraulic and refrigerant applications where overpressure resilience is critical. This range is fixed per die and cannot be reconfigured in the field.
Does the MLX90820LUF-EBB-000-WB support both analog and SENT outputs simultaneously?
No - the MLX90820LUF-EBB-000-WB operates in either analog mode (using the OUT pin) or SENT mode (using the TX pin), but not both concurrently. The mode is selected via external circuit configuration: connecting OUT to load enables analog output; connecting TX to SENT receiver enables digital output. Internal logic disables the inactive path to minimize power and noise coupling.
How is the MLX90820LUF-EBB-000-WB protected against oil contamination?
The MLX90820LUF-EBB-000-WB features a passivated die surface and proprietary backside sealing that prevents hydrocarbon absorption and electrical charge buildup from mineral oils, synthetic esters, and refrigerant oils. This oil charge immunity is validated per Melexis internal test protocol and enables stable long-term drift performance (<0.2% FSO/year) in oil-filled modules without additional barrier layers.
Can the MLX90820LUF-EBB-000-WB be used without external capacitors?
No - the MLX90820LUF-EBB-000-WB requires two minimum external capacitors: a 47 nF decoupling capacitor on VDD and a 47 nF load capacitor on the OUT pin for analog mode (or 2.2 nF on TX for SENT mode). These are mandatory for stable regulation, noise suppression, and SENT timing compliance per SAE J2716. Omitting them causes output instability and EMC failures.
Is the MLX90820LUF-EBB-000-WB delivered as a packaged IC or bare die?
The MLX90820LUF-EBB-000-WB is delivered as bare die on fully tested wafers (package code "UF") in wafer box (WB) format, accompanied by an electronic wafer map. It is not supplied in molded plastic or ceramic packages. Customers must integrate it using flip-chip or wire-bond assembly into custom housings - typically oil-filled stainless-steel or ceramic pressure modules.
