Product details

Overview

MLX90295EVC-FAA-000-BU from Melexis is a programmable ratiometric linear Hall effect sensor IC with quad switched Hall plate, chopper-stabilized amplifier, and EEPROM-based calibration. It delivers analog output voltage proportional to magnetic flux density (±20 mT typical range) and supply voltage (4.5–5.5 V), featuring programmable VOQ (−100% to 200% VDD), sensitivity (2.6–15 mV/mT for FAA-000 variant), and thermal compensation. It is used in automotive throttle position sensing where high-temperature stability (−40°C to 150°C) and field-programmable offset/slope are critical.

For engineers reviewing the MLX90295EVC-FAA-000-BU datasheet, pinout, applications, or equivalent options, key selection considerations include its VC-package 4-pin SOT-23-4L footprint, PTC programming interface, ratiometric output behavior under supply variation, and FAA-000–specific sensitivity range optimized for 333–800 mT magnetic fields.

Technical Context

The MLX90295EVC-FAA-000-BU integrates a temperature-compensated quad Hall plate with chopper stabilization to suppress offset drift, and uses internal DACs to configure gain, clamping, and filtering via EEPROM. Its signal chain includes a programmable rough gain stage (RG = 0–3 for FAA-000), fine gain (10-bit FG), and dual-stage low-pass filter (FILTER = 0–15).

Programming occurs via Melexis' PTC serial interface, enabling in-system calibration of VOQ, sensitivity polarity (INVERT), clamping levels (CLAMPLOW/CLAMPHIGH), and first-/second-order temperature compensation (TC/TC2/TCW). All parameters are stored in redundant EEPROM with parity and CRC protection, and locked via MEMLOCK after configuration.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5–5.5 V - Enables direct interfacing with standard 5 V microcontroller ADC references without external regulation.
Ratiometric Output	VOUT = VOQ + Sensitivity × B - Output scales with VDD; ±10% supply fluctuation is inherently compensated when using VDD as ADC reference.
Sensitivity Range (FAA-000)	2.6–15 mV/mT - Optimized for magnetic fields of 333–800 mT; supports unipolar linear position sensing with wide air-gap tolerance.
VOQ Programmability	−100% to 200% VDD - Allows zero-field output tuning from 0 V to full rail, eliminating need for external level-shifting circuitry.
Operating Temperature	−40°C to 150°C - Qualified for under-hood automotive applications including engine control and transmission sensors.
Thermal VOQ Drift	±0.4% VDD (−40°C to 150°C) - Achieved via factory-trimmed DRIFT parameter; ensures <10 mV absolute offset error over full range.
Output Clamping	Programmable CLAMPLOW/CLAMPHIGH (0–100% VDD) - Prevents saturation-induced nonlinearity; default 50% VDD enables symmetric swing around quiescent point.

Pinout & Package

MLX90295EVC-FAA-000-BU uses the VC package: plastic single-in-line (SIL) with 0.9–1.0 mm thickness, 4-pin SOT-23-4L outline, Hall plate centered beneath die top surface per Melexis Package Outline Drawing.

Pin/Terminal	Circuit Role	Design Meaning
VDD	Positive supply input	Accepts 4.5–5.5 V; includes overvoltage detection (6.5–8.5 V) and power-on reset (1.5–3.8 V).
Test	PTC programming interface	Serial bidirectional pin for in-circuit EEPROM programming; requires Melexis PTC hardware and protocol.
VSS	Ground reference	Return path for supply and output; diagnostic mode detects open-ground fault via VOUT2/VOUT4 voltage thresholds.
VOUT	Analog output driver	Ratiometric linear voltage output (2–97% VDD swing); supports 10 kΩ pull-up/down loads; short-circuit tolerant (±12 mA).

Key Features

Feature	Design Value
Quad switched Hall plate	Reduces mechanical stress-induced offset and eliminates 1/f noise; enables stable DC magnetic field measurement at 0 Hz.
Chopper-stabilized amplifier	Active offset correction reduces initial offset to <1 mT equivalent and suppresses thermal drift below 0.4% VDD over −40°C to 150°C.
EEPROM-based programmability	128-row × 4-column redundant memory stores VOQ, sensitivity, clamping, filter, and TempCo settings; majority-voting prevents single-point failure.
PTC programming interface	Single-wire in-system programming allows end-of-line calibration without removing device from PCB; supports traceability via Melexis ID and 24-bit CUSTID.
Diagnostic output states	Four fault voltages (VOUT1–VOUT4) indicate broken supply/ground; FAULTLEV configures parity-error response as high/low clamp.

Equivalent & Alternatives

The following parts are listed as comparable options for similar linear Hall effect sensor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90363KDC-ABA-000-TU	Triaxis 3D Hall sensor with SPI digital output; no analog ratiometric output; higher resolution (16-bit) but requires MCU interface.	Used where vector field direction matters (e.g., joystick, 3D position); not drop-in for analog-only systems requiring VOUT pin compatibility.	Select when directional sensing or digital communication is required; avoid if legacy 5 V analog ADC interface must be preserved.
Allegro A1308LLHLT-T	Fixed-sensitivity (5.0 mV/G) linear Hall IC; no EEPROM, no programmable VOQ/clamp/filter; simpler but less flexible calibration.	Suitable for cost-sensitive consumer applications with stable mechanical design; lacks thermal drift compensation and field-range optimization of FAA-000.	Select for production simplicity and lower BOM cost where magnetic field and temperature variation are tightly controlled.

Compared with MLX90295EVC-FAA-000-BU, MLX90363KDC-ABA-000-TU offers digital 3D field data but requires redesign of signal chain and firmware, while A1308LLHLT-T provides plug-and-play analog operation at the expense of field-programmable accuracy and thermal robustness.

FAQ

What is the meaning of "FAA-000" in MLX90295EVC-FAA-000-BU?

The "FAA-000" suffix in MLX90295EVC-FAA-000-BU specifies the sensitivity range option code: it denotes Rough Gain setting 0–3, optimized for 2.6–15 mV/mT sensitivity and magnetic fields of 333–800 mT. This variant is factory-characterized for best TempCo performance within that range and is distinct from FAA-100, FAA-200, and FAA-300 variants.

Can MLX90295EVC-FAA-000-BU operate with a 3.3 V supply?

No - MLX90295EVC-FAA-000-BU is specified for 4.5–5.5 V operation only. Its internal bandgap reference, chopper clock, and output driver are designed for 5 V nominal supply; operation below 4.5 V may cause undefined behavior, failed power-on reset, or loss of ratiometric accuracy. For 3.3 V systems, consider Melexis MLX90393 or alternative 3.3 V–compatible Hall sensors.

How is programming performed on MLX90295EVC-FAA-000-BU?

Programming is performed via the Test pin using Melexis' PTC (Programming Through the Connector) protocol - a single-wire, half-duplex serial interface requiring dedicated PTC hardware (e.g., EVB90295 evaluation board) and Melexis PTC software. Parameters like VOQ, sensitivity, clamping, and TempCo are written to redundant EEPROM with parity/CRC validation; MEMLOCK prevents further writes after final calibration.

Does MLX90295EVC-FAA-000-BU support bidirectional magnetic field sensing?

Yes - MLX90295EVC-FAA-000-BU supports bidirectional sensing via the INVERT bit: when INVERT = 0, VOUT increases with South pole field perpendicular to top face; when INVERT = 1, VOUT increases with North pole field. Combined with programmable VOQ (−100% to 200% VDD), it enables full-rail symmetric output for ±mT field measurement without external op-amps.

What is the role of the "Test" pin on MLX90295EVC-FAA-000-BU?

The Test pin on MLX90295EVC-FAA-000-BU serves exclusively as the PTC programming interface - it is not a test point for functional verification or debug. During normal operation, it must be left floating or pulled to VDD/VSS via ≥100 kΩ resistor; active driving or AC coupling will disrupt EEPROM programming or cause communication failure. No analog/digital signal is present on this pin outside PTC mode.
