Product details

Overview

MLX90818LXE-BBG-015-RE from Melexis is an automotive-grade absolute pressure sensor delivering SENT digital output, calibrated for 0.1–4 bar absolute pressure range with ±0.5% FS accuracy over –40°C to 150°C, integrated MEMS sensing element, 16-bit microcontroller, and on-chip voltage regulation - deployed in turbo manifold air pressure monitoring systems.

For engineers reviewing the MLX90818LXE-BBG-015-RE datasheet, pinout, applications, or equivalent options, key selection criteria include SENT protocol compliance (SAE J2716), factory-programmed transfer curve (193–3896 LSB), absence of NTC interface, and DFN14 package suitability for high-vibration engine bay environments.

Technical Context

The MLX90818LXE-BBG-015-RE implements a piezoresistive Wheatstone bridge MEMS element with wafer-bonded vacuum reference cavity, coupled to a 16-bit DSP-based microcontroller performing real-time gain/offset temperature compensation and pressure linearization. Its analog front end includes programmable gain stages (Gst1 = 4.49–10.6 V/V) and chopper-stabilized instrumentation amplification.

Digital functionality includes SENT frame generation (fast channel only), EEPROM-stored calibration coefficients (O0–O3, G0–G3), and dual-stage filtering (PFLT programmable low-pass + SSF small-signal bypass). Diagnostics cover overvoltage, reverse voltage, broken wire, and supply POR detection - all configurable via EEPROM.

Response Time	3 SENT frames (≈9 µs at 3 µs tick time) - achieved with PFLT = 0 and SSF disabled per default configuration

Pinout & Package

MLX90818LXE-BBG-015-RE uses a 14-pin DFN package (4×5 mm, 0.5 mm pitch) with wettable flank leads and exposed thermal pad. Pin 1 is marked by laser etching on top surface; bottom view shows pins arranged in two rows (1–7 top, 8–14 bottom).

Pin/Terminal	Circuit Role	Design Meaning
1	Test pin	Factory test access; not connected in normal operation; must be left floating or grounded per layout guidelines
3	SENT output	Open-drain SENT signal driver with slew-rate control; requires external 10–55 kΩ pull-up to Vdd at receiver
7	Supply input	Main 4.5–5.5 V power input; decoupling capacitor (100 nF) required within 2 mm of pin
10, 14	Ground	Dual GND terminals for analog/digital separation; both must be connected to low-impedance PCB ground plane
2, 4, 6, 11, 13	Not Connected	No internal connection; must remain unconnected on PCB; no routing or copper fill allowed
8, 12	NTC input	Not used in BBG-015 variant - pins are internally disconnected; must be left floating per datasheet

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar absolute pressure sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90818LXE-BBG-016-RE	Includes NTC interface (pins 8/12 active); same 0.1–4 bar pressure range but 0.1–3 bar calibrated span; ±15 mBar pressure accuracy	Required when simultaneous intake air temperature measurement is needed alongside pressure; supports dual-sensor replacement	Select BBG-016 if NTC integration reduces system cost versus discrete thermistor + ADC solution
MPX5700A	Analog output (0.2–4.7 V ratiometric); no SENT, no microcontroller, no diagnostics; 70°C max operating temp; TO-92 package	Limited to non-critical, low-temperature applications like HVAC or industrial air compressors; lacks automotive qualification	Choose MPX5700A only for cost-sensitive, non-automotive designs where digital interface and extended temperature are unnecessary

Compared with MLX90818LXE-BBG-015-RE, BBG-016 adds NTC capability at identical pressure range and packaging but trades 5 mBar pressure accuracy for temperature sensing; MPX5700A offers lower unit cost but requires external signal conditioning, fails automotive temperature and diagnostic requirements, and lacks SENT compatibility for modern ECU interfaces.

FAQ

What is the pressure measurement range and accuracy of the MLX90818LXE-BBG-015-RE?

The MLX90818LXE-BBG-015-RE is factory calibrated for 0.1 to 4 bar absolute pressure with ±0.5% full-scale accuracy over –40°C to +150°C. Its output spans 193 to 3896 LSB in SENT format, yielding 3703 LSB/bar resolution. Accuracy remains stable over life due to MEMS die assembly and DSP-based temperature compensation embedded in the MLX90818LXE-BBG-015-RE.

Does the MLX90818LXE-BBG-015-RE support NTC temperature sensing?

No, the MLX90818LXE-BBG-015-RE variant does not include NTC functionality. Pins 8 and 12 are internally disconnected and must be left floating on the PCB. NTC capability is only present in BBG-016 and BBG-017 variants. The MLX90818LXE-BBG-015-RE retains the on-chip PTAT temperature sensor (±10°C accuracy) for internal diagnostics but excludes external thermistor interface.

What SENT protocol version and frame structure does the MLX90818LXE-BBG-015-RE implement?

The MLX90818LXE-BBG-015-RE complies with SAE J2716 APR2016 SENT standard. It transmits pressure data exclusively in the fast channel (12 bits), with no slow channel or CRC nibble enabled in default BBG-015 configuration. Frame timing uses 3 µs tick time and pause pulse mode, delivering deterministic 125 Hz update rate with 3-frame (≈9 µs) response latency when PFLT = 0.

How is the MLX90818LXE-BBG-015-RE protected against electrical stress in automotive environments?

The MLX90818LXE-BBG-015-RE integrates overvoltage protection up to +18 V and reverse voltage tolerance down to –18 V on the supply pin, plus broken-wire detection on SENT output and analog inputs. Its analog/digital regulators include POR circuitry with 3.1–3.9 V rising threshold and 100–500 mV hysteresis. These protections are inherent to the MLX90818LXE-BBG-015-RE silicon design and require no external components.

Can the MLX90818LXE-BBG-015-RE be reprogrammed in-system for custom calibration curves?

Yes, the MLX90818LXE-BBG-015-RE supports in-system programming via its SENT interface using Melexis' proprietary communication protocol. Customers can overwrite EEPROM calibration coefficients (O0–O3, G0–G3, L0–L1) and filter settings (PFLT, SSF) through the supply pin using 6.2–7.8 V programming entry level. This capability enables field calibration adaptation without replacing the MLX90818LXE-BBG-015-RE.
