Product details

Overview

MLX90614ESF-ABA-000-SP from Melexis is a factory-calibrated, single-zone infrared thermometer IC in TO-39 metal can package, integrating thermopile detector and signal-conditioning ASSP. It delivers ±0.5°C accuracy for ambient/object temperatures (0°C–50°C), 0.02°C measurement resolution, SMBus-compatible digital interface, and programmable PWM output. Used in non-contact thermal sensing for automotive HVAC, medical thermometry, and industrial temperature control.

For engineers reviewing the MLX90614ESF-ABA-000-SP datasheet, pinout, applications, or equivalent options, this page provides verified technical context, pin-level design meaning, real-world application mappings, and validated alternative options for thermal sensing system integration.

Technical Context

The MLX90614ESF-ABA-000-SP implements a chopper-stabilized low-noise amplifier, 17-bit sigma-delta ADC, and on-chip DSP to compute ambient (Ta) and object (To) temperatures from thermopile voltage. Its internal EEPROM stores calibration coefficients, emissivity (default 1.0), and user-configurable PWM range parameters.

It operates as an SMBus slave device with fixed 0x5A address, supports thermal relay mode via PWM pin, and features POR circuitry with 1.4–1.95 V threshold. The ABA suffix confirms 5.0 V supply (Axx), -40°C to +85°C ambient rating (E), TO-39 package (SF), and standard emissivity configuration (000).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5–5.5 V - compatible with standard 5 V systems; zener clamp (5.7 V) on SCL protects against overvoltage.
Ambient Temp Range	-40°C to +85°C - defines operating envelope for sensor electronics; matches ESF temperature grade.
Object Temp Range	-70°C to +380°C - usable field-of-view temperature span; full range supported without recalibration.
Accuracy (Ta/To)	±0.5°C at 0°C–50°C - guaranteed under isothermal conditions; requires thermal shielding for best performance.
Output Resolution	0.02°C (SMBus), 0.14°C (PWM) - SMBus delivers high-precision digital values; PWM provides analog-like continuous output.
Interface	SMBus 2-wire (10–100 kHz), 10-bit PWM - dual-mode communication; SMBus default at power-on; PWM configurable via EEPROM.
Current Consumption	1.3–2.5 mA active, no sleep mode - consistent with Axx 5 V variant; sleep unavailable per datasheet Note 6.

Pinout & Package

MLX90614ESF-ABA-000-SP uses the industry-standard 4-pin TO-39 metal can package (Ø5.6 mm × 8.5 mm height), with hermetically sealed IR window and integrated long-wave pass optical filter (5.5–14 µm). The metal can must connect only to VSS to maintain isothermal integrity and EMC compliance.

Pin/Terminal	Circuit Role	Design Meaning
1: SCL / Vz	SMBus clock input / Zener clamp	Accepts 10–100 kHz clock; internal 5.7 V zener protects against overvoltage on 5 V systems.
2: SDA / PWM	SMBus data I/O or PWM output	Configurable dual-function pin; defaults to SMBus after POR; supports thermal relay mode when reprogrammed.
3: VDD	Positive supply	4.5–5.5 V input; powers internal regulator, ADC, DSP, and interface logic; no external decoupling specified but recommended.
4: VSS	Ground reference	Single-point connection to metal can required; avoids thermal gradients and noise coupling into thermopile measurement path.

Key Features

Feature	Design Value
Factory calibration	Delivers absolute Ta and To readings without user calibration; valid across -40°C to +125°C ambient and -70°C to +380°C object ranges.
Programmable emissivity	EEPROM-stored 16-bit value (0x0000–0xFFFF) enables accurate compensation for materials with ε = 0.1–1.0 without black-body recalibration.
Thermal relay mode	PWM pin reconfigured as comparator output; user-programmable To threshold triggers interrupt-capable alert for thermostat or freeze-detection use.
Optical filtering	Integrated long-wave pass filter (5.5–14 µm) rejects visible/NIR radiation, ensuring immunity to ambient light and sunlight interference.
High-voltage adaptation	Supports 8–16 V operation using external resistor-zener network on VDD; preserves SMBus compatibility without level-shifting.

Equivalent & Alternatives

The following parts are listed as comparable options for similar non-contact infrared temperature sensing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MLX90614ESF-BAA-000-SP	3.0 V supply (Bxx), same TO-39 package and -40°C to +85°C ambient rating; includes sleep mode (2–6 µA).	Better suited for battery-powered portable devices; lacks 5.7 V zener on SCL; lower drive strength on SDA/SCL.	Select when low quiescent current and 3 V operation are mandatory; not drop-in compatible due to supply and interface voltage differences.
MLX90614KSF-ACA-000-SP	Extended ambient range (-40°C to +125°C, K grade); 5.0 V supply (Axx); identical pinout, SMBus, and PWM functionality.	Required for under-hood automotive or high-ambient industrial environments where >85°C operation occurs.	Drop-in replacement if ambient temperature exceeds +85°C; otherwise identical electrical and functional behavior to MLX90614ESF-ABA-000-SP.

Compared with MLX90614ESF-ABA-000-SP, the BAA variant trades 5 V robustness and zener protection for ultra-low sleep current, while the KSF variant extends ambient tolerance to +125°C with no other changes-making it the only true pin-and-function compatible upgrade path for high-temperature deployments.

FAQ

What is the operating temperature range for the MLX90614ESF-ABA-000-SP ambient sensor?

The MLX90614ESF-ABA-000-SP has an ambient temperature operating range of -40°C to +85°C, as defined by the 'E' grade in its part number. This rating applies to the sensor's internal electronics and is validated per AEC-Q100 stress testing. Operation outside this range may cause measurement drift or permanent damage, and is not covered by factory calibration.

Does the MLX90614ESF-ABA-000-SP support sleep mode?

No, the MLX90614ESF-ABA-000-SP does not support sleep mode. Sleep functionality is exclusive to the 3.0 V Bxx variants (e.g., MLX90614ESF-BAA-000-SP), as explicitly stated in datasheet Note 6. The ABA suffix confirms it is a 5.0 V Axx version, which draws 1.3–2.5 mA continuously during operation.

Can the MLX90614ESF-ABA-000-SP measure object temperature beyond 100°C?

Yes, the MLX90614ESF-ABA-000-SP supports object temperature measurements from -70°C to +380°C. Its full-range capability is enabled by factory calibration and on-chip DSP processing; no firmware or external scaling is needed. Accuracy remains ±0.5°C only within 0°C–50°C, but extended-range readings remain repeatable and usable for relative trending or alarm triggering.

How is emissivity configured on the MLX90614ESF-ABA-000-SP?

Emissivity is stored as a 16-bit value in EEPROM address 0x04 and defaults to 0xFFFF (ε = 1.0). Users can write any value between 0x0666 (ε = 0.1) and 0xFFFF (ε = 1.0) via SMBus. The conversion uses Emissivity = round(65535 × ε), and erase-before-write is required. No black-body recalibration is needed after update.

Is the MLX90614ESF-ABA-000-SP pin-compatible with other MLX90614 variants in TO-39?

Yes, all MLX90614 variants in SF (TO-39) package-including MLX90614ESF-ABA-000-SP, MLX90614ESF-BAA-000-SP, and MLX90614KSF-ACA-000-SP-share identical 4-pin TO-39 pinout, mechanical footprint, and solder pad layout. However, electrical compatibility depends on supply voltage, zener presence, and sleep capability; direct substitution requires verification of system-level voltage and power constraints.
