Product details

Overview

MLX90820LUF-EBB-000-SP from Melexis is an automotive-grade absolute pressure sensor IC delivering ratiometric analog and SENT outputs, with 30–50 bar full-scale range, ±0.2% FSO non-linearity at room temperature, and operation from −40°C to +150°C - deployed in engine oil pressure monitoring and industrial hydraulic systems.

For engineers reviewing the MLX90820LUF-EBB-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its integrated SENT v2010 compliance, programmable diagnostics (broken track, clamping), 16-bit microcontroller-based compensation, and bare-die UF package for direct die bonding in miniaturized modules.

Technical Context

The MLX90820LUF-EBB-000-SP integrates a piezoresistive silicon diaphragm, analog front-end with coarse offset correction, 16-bit microcontroller-based DSP for temperature-compensated linearization, and dual-output analog back-end (12-bit DAC) plus SENT driver compliant with SAE J2716 Jan 2010. It implements real-time diagnostics including over/under-pressure detection and supply rail fault sensing.

Its architecture supports field-programmable EEPROM settings for clamping thresholds (8-bit low / 9-bit high), filter coefficients (SSF=1, PFLT=0 default), and diagnostic enablement - all accessible via dedicated TEST pad during programming, with built-in EE memory protection and reverse-polarity/overvoltage robustness up to −14 V at 150°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Pressure Range	30–50 bar full-scale output span, calibrated for EBB-000 option - defines usable pressure window without signal saturation.
Non-Linearity Error	±0.2% FSO at room temperature (30/50 bar calibration points) - ensures high fidelity across mid-pressure industrial and automotive use cases.
Output Types	Ratiometric analog (OUT pin) and SENT digital (TX pin) - enables dual-mode system integration with legacy analog gauges or modern CAN/Sent networks.
Operating Temp	−40°C to +150°C - qualified for under-hood automotive locations and high-temp industrial oil-filled modules.
Supply Voltage	4.5–5.5 V nominal, with reverse voltage tolerance to −14 V at 150°C for 1 hour - eliminates need for external reverse-polarity protection.
Response Time	Analog: 1 ms (10–90%); SENT: 3–4 frames (3 µs tick time) - supports fast-cycling hydraulic control and real-time engine management feedback.
EMC Robustness	Automotive-grade immunity per ISO 11452 and ISO 7637 - validated for harsh environments without additional shielding or filtering.

TX	SENT digital output	Sent protocol output (SAE J2716 v2010 compliant); driven only in SENT mode; requires 2.2 nF capacitive load.
TEST	Programming input	Used for EEPROM configuration and firmware update; must be left unconnected in final application.
SN / SP	Reserved test pads	No functional connection in production; designated "Do Not Connect" per datasheet Table 3.

Key Features

Feature	Design Value
Integrated MEMS + AFE + DSP + SENT driver	Single-die solution eliminates external signal conditioning, reducing BOM count and PCB footprint in compact pressure modules.
Programmable diagnostics	Configurable clamping levels, broken-track detection, and over/under-pressure alerts stored in protected EEPROM - enables OEM-specific fault response logic.
Oil-charge immunity	Robust passivation and layout design prevent performance drift in oil-filled industrial transducers exposed to long-term hydrocarbon contact.
High EMC resilience	Optimized CMOS architecture and internal filtering meet automotive EMC requirements without external ferrites or shielding components.
16-bit microcontroller compensation	Real-time temperature and pressure linearization delivers ±0.2% FSO accuracy across −40°C to +150°C - outperforms analog-only sensors in thermal stability.

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	Legacy analog-only output (no SENT), wider 0–700 kPa range, no programmable diagnostics or EEPROM.	Lacks digital diagnostics and automotive-grade temperature range (−40°C to +125°C only).	Choose MPX5700AP only for cost-sensitive, non-diagnostic analog-only systems where SENT or extended temp is unnecessary.
TDK InvenSense ICP-10125	I²C digital output only, 10–100 kPa range, lower max temp (−40°C to +85°C), no analog output or oil immunity.	Not rated for oil immersion or automotive under-hood use; limited to consumer/industrial air pressure sensing.	Select ICP-10125 for low-power, I²C-based environmental monitoring - not suitable for hydraulic or engine oil applications.

Compared with MPX5700AP and ICP-10125, the MLX90820LUF-EBB-000-SP uniquely combines 30–50 bar range, SENT+analog dual output, oil-charge immunity, and −40°C to +150°C operation - making it the only viable choice for automotive oil pressure and industrial oil-filled transducers requiring field-programmable diagnostics.

FAQ

What is the pressure range supported by MLX90820LUF-EBB-000-SP?

The MLX90820LUF-EBB-000-SP is factory-configured for a 30–50 bar absolute pressure range, as specified by the EBB-000 option code. This range is calibrated at 30 bar and 50 bar endpoints, delivering ±0.2% FSO non-linearity at room temperature. It is not user-reconfigurable to other spans without reprogramming EEPROM settings and recalibration.

Does MLX90820LUF-EBB-000-SP support both analog and digital outputs simultaneously?

No - the MLX90820LUF-EBB-000-SP supports either analog (via OUT pin) or SENT (via TX pin) output at any given time, determined by external circuit configuration and EEPROM settings. Both outputs share the same pressure data path but require separate load components: 47 nF for analog mode, 2.2 nF for SENT mode.

How is MLX90820LUF-EBB-000-SP protected against oil contamination in industrial modules?

The MLX90820LUF-EBB-000-SP features proprietary passivation and bond pad layout designed to resist dielectric charging from silicone or mineral oils. Its UF bare-die form allows direct encapsulation in oil-filled cavities without performance degradation over time - validated per Melexis internal oil-immersion reliability testing protocols.

What diagnostic functions are enabled by default on MLX90820LUF-EBB-000-SP?

By default, MLX90820LUF-EBB-000-SP enables broken-track detection, over/under-voltage monitoring, and basic clamping (low/high thresholds set to 3% and 96% VDD). Full diagnostic suite - including over/under-pressure alerts and programmable clamping - requires EEPROM configuration via the TEST pad using Melexis-provided tools.

Is MLX90820LUF-EBB-000-SP supplied in tape-and-reel or wafer form?

MLX90820LUF-EBB-000-SP is supplied as a sawn wafer in a wafer box (WB packing form), with electronic wafer map included. It is not offered in tape-and-reel or molded packages - the UF designation confirms bare-die delivery for customer die-bonding into custom housings or modules.
