Product details
Overview
MLX90614ESF-BCK-000-SP from Melexis is a factory-calibrated, single-zone infrared thermometer IC in TO-39 metal can package, delivering ±0.5°C accuracy for ambient and object temperature over 0°C–50°C, 0.02°C measurement resolution in SMBus mode, and dual-output capability via SMBus or configurable 10-bit PWM - used in automotive blind-angle detection, thermal comfort control, and medical-grade body temperature sensing.
For engineers reviewing the MLX90614ESF-BCK-000-SP datasheet, pinout, applications, or equivalent options, key selection factors include its -40°C to +125°C operating ambient range, 3.0V supply compatibility, SMBus slave address 0x5A, integrated optical long-wave pass filter (5.5–14 µm), and thermal gradient compensation in Cx variants - critical for non-contact industrial and automotive thermal monitoring where isothermal mounting is constrained.
Technical Context
The MLX90614ESF-BCK-000-SP integrates a thermopile detector and signal-conditioning ASSP in one TO-39 package, using a low-noise chopper amplifier, 17-bit sigma-delta ADC, and programmable DSP to compute ambient (Ta) and object (To) temperatures with 0.01°C internal resolution. Its factory calibration covers Ta from -40°C to +125°C and To from -70°C to +380°C.
It supports two digital interfaces: SMBus (default power-on mode, 10–100 kHz, slave address 0x5A) and user-configurable 10-bit PWM (1.024 ms period, 0.14°C resolution in default -20°C to +120°C range). Sleep mode draws 2–6 µA and is enabled only on 3.0V Bxx variants like this part - not available on 5.0V Axx versions.
Key Specifications

| SMBus Address | 0x5A (7-bit) - fixed slave address simplifies multi-sensor bus configuration with up to 127 devices. |
| Power Consumption | 1.3–2.5 mA active, 2–6 µA sleep - enables always-on thermal sensing in energy-constrained IoT and portable medical devices. |
Pinout & Package
MLX90614ESF-BCK-000-SP uses the industry-standard 4-pin TO-39 metal can package (SF code), with hermetically sealed IR window and integrated long-wave pass optical filter (5.5–14 µm). The metal can must connect only to VSS for EMC and thermal stability; no other electrical connection is permitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SCL / Vz | SMBus clock input / Zener clamp | Accepts 10–100 kHz SMBus clock; includes 5.7 V zener for overvoltage protection on Axx variants - not present on Bxx (3.0 V) variants like this part. |
| 2: SDA / PWM | Bi-directional data I/O or PWM output | Configurable as SMBus data line (open-drain) or 10-bit PWM output; defaults to SMBus after POR; supports thermal relay mode. |
| 3: VDD | Positive supply | 3.0 V nominal input (2.6–3.6 V range); powers internal regulator, DSP, and EEPROM; enables sleep mode entry. |
| 4: VSS | Ground reference | Primary ground return; sole electrical connection allowed to TO-39 metal can - mandatory for thermal equilibrium and EMC compliance. |
Key Features
| Feature | Design Value |
|---|---|
| Factory calibration | Pre-programmed Ta/To coefficients stored in EEPROM eliminate field calibration; valid across full -40°C to +125°C ambient range. |
| Thermal gradient compensation | Internal TGC (Temperature Gradient Compensation) logic reduces error from package thermal gradients - critical for compact enclosures with nearby heat sources. |
| User-programmable emissivity | Emissivity value (0.1–1.0) stored in EEPROM address 0x04; allows accurate readings on non-blackbody surfaces (e.g., plastic, painted metal) without recalibration. |
| Configurable PWM output | Two EEPROM registers (0x00–0x01) define custom To range and resolution; enables direct interface to microcontrollers lacking SMBus hardware. |
| Thermal relay function | PWM pin reconfigurable as open-drain thermal alert output; user-defined threshold triggers interrupt-capable thermostatic response without host CPU polling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar non-contact IR temperature sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MLX90614ESF-BCI-000-TU | Same TO-39 package and 3.0 V supply, but features uncoated silicon lens (no long-wave pass filter); wider spectral response (1–14 µm) increases ambient light sensitivity. | Preferred for indoor lab environments with controlled lighting; unsuitable for direct sunlight or automotive exterior use due to visible/NIR interference. | Select when spectral flexibility outweighs ambient immunity; verify optical path shielding if used outdoors. |
| AMG8833 | 8×8 thermal array (64 pixels) vs. single-point MLX90614; I²C interface only; lower accuracy (±2.5°C); requires external optics and calibration. | Used for thermal imaging (presence detection, gesture control), not precision spot measurement; needs host processor for pixel processing. | Choose for spatial thermal mapping; avoid when single-point accuracy, SMBus compatibility, or drop-in replacement is required. |
Compared with MLX90614ESF-BCK-000-SP, the BCJ variant trades optical filtering for broader spectrum response - limiting outdoor reliability - while the AMG8833 provides imaging capability at the cost of accuracy, interface simplicity, and calibration stability, making it unsuitable as a functional substitute in precision thermometry applications.

FAQ
What is the operating voltage range for MLX90614ESF-BCK-000-SP?
The MLX90614ESF-BCK-000-SP operates from 2.6 V to 3.6 V, optimized for 3.0 V systems such as battery-powered medical devices or automotive body controllers. It does not support 5.0 V operation - that variant is designated MLX90614Axx. Exceeding 3.6 V may cause permanent damage per absolute maximum ratings.
Does MLX90614ESF-BCK-000-SP support sleep mode?
Yes, MLX90614ESF-BCK-000-SP supports sleep mode with 2–6 µA typical current draw, activated via SMBus command or hardware reset sequence. Sleep mode is exclusive to 3.0 V Bxx variants like this part and is not available on 5.0 V Axx versions. Wake-up time is 33 ms after SDA low pulse.
What is the field of view (FOV) of MLX90614ESF-BCK-000-SP?
The MLX90614ESF-BCK-000-SP has a 35° full-angle field of view, defined by its integrated silicon lens and TO-39 package geometry. This FOV is fixed per variant and cannot be altered mechanically or electrically. Accuracy specifications assume uniform target filling the entire FOV; partial coverage introduces measurement uncertainty.
Can MLX90614ESF-BCK-000-SP measure human body temperature accurately?
Yes, MLX90614ESF-BCK-000-SP achieves ±0.5°C accuracy in the 0°C–50°C range - covering human body temperature (35°C–42°C) - when mounted under isothermal conditions and with proper emissivity setting (ε ≈ 0.97–0.98 for skin). For regulatory-grade clinical use, Melexis offers a dedicated medical accuracy version (±0.2°C), but MLX90614ESF-BCK-000-SP meets general wellness screening requirements.
How is emissivity configured on MLX90614ESF-BCK-000-SP?
Emissivity is stored as a 16-bit value in EEPROM address 0x04, with factory default 0xFFFF (ε = 1.0). Users write scaled integer values using SMBus: ε = round(65535 × desired_emissivity), e.g., 0xF5AD for ε = 0.95. Write requires prior erase; no black-body recalibration is needed, and changes persist across power cycles.
