Product details
Overview
MLX90614ESF-DCI-000-SP from Melexis is a factory-calibrated, single-zone infrared thermometer IC in TO-39 metal can package, delivering ±0.5°C accuracy (0°C to +50°C) for both ambient and object temperature, 0.02°C measurement resolution via SMBus, and dual-output capability (SMBus + configurable PWM). It operates from 3.0V or 5.0V supply and is used in non-contact thermal sensing for automotive HVAC, medical thermometry, and industrial process monitoring.
For engineers reviewing the MLX90614ESF-DCI-000-SP datasheet, pinout, applications, or equivalent options, key selection criteria include its -40°C to +125°C ambient operating range, -70°C to +380°C object temperature range, SMBus slave address 0x5A, 10-bit PWM output with 1.024 ms period, and thermal gradient compensation enabled by the "CI" variant's internal gradient sensing.
Technical Context
The MLX90614ESF-DCI-000-SP integrates a thermopile IR detector and signal-conditioning ASSP on a single die inside a TO-39 can, featuring a low-noise chopper amplifier, 17-bit sigma-delta ADC, and programmable DSP for real-time ambient (Ta) and object (To) temperature computation. Its internal EEPROM stores calibration coefficients, emissivity (default 1.0), and user-configurable PWM range parameters.
It supports two communication modes: SMBus (factory default, 10–100 kHz, open-drain SDA/SCL) and free-running 10-bit PWM (1.024 ms period, ±10% stability over temperature/voltage). The "CI" suffix denotes integrated thermal gradient compensation-critical for stable readings under non-isothermal PCB conditions-and distinguishes it from standard "SF" or "CF" variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Ambient Temp Range | -40°C to +125°C - Enables operation in under-hood automotive or industrial control environments. |
| Object Temp Range | -70°C to +380°C - Supports wide-range non-contact sensing including freezer monitoring and hot surface detection. |
| Accuracy (Ta/To) | ±0.5°C at 0°C–50°C - Validated for clinical-grade thermal comfort and HVAC feedback loops. |
| Resolution (SMBus) | 0.02°C - Enables fine-grained temperature trending and closed-loop control precision. |
| Supply Voltage | 3.0V or 5.0V - Dual-voltage support simplifies integration into battery-powered (Bxx) or 5V microcontroller systems (Axx). |
| Current Consumption | 1.3–2.5 mA active; 2–6 µA sleep (Bxx only) - Low power enables always-on thermal monitoring in portable devices. |
| SMBus Address | 0x5A (7-bit) - Fixed slave address allows multi-sensor bus configuration up to 127 nodes with pull-up tuning. |
| PWM Period | 1.024 ms (±10%) - RC oscillator-based timing enables simple microcontroller capture without external clock source. |
Pinout & Package
Package: TO-39 metal can with integrated long-wave IR optical filter (5.5 µm–14 µm passband), hermetically sealed, industry-standard 4-pin leaded package. Pin 1 marked by dot; can electrically connected only via VSS (pin 4) per EMC and isothermal requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: SCL / Vz | SMBus clock input / Zener clamp | 5.7 V zener protection on Axx versions; functions as clock line in SMBus mode; must be pulled up externally. |
| 2: SDA / PWM | SMBus data I/O or PWM output | Bidirectional pin: acts as open-drain data line in SMBus; outputs 10-bit duty-cycle modulated temperature in PWM mode. |
| 3: VDD | Positive supply | Accepts 3.0V (Bxx) or 5.0V (Axx); supports 8–16V operation with external components per datasheet Section 5.5. |
| 4: VSS | Ground reference | Only electrical connection point to metal can; critical for thermal equilibrium and EMC performance. |
Key Features
| Feature | Design Value |
|---|---|
| Factory calibration | Pre-programmed Ta/To coefficients stored in EEPROM eliminate need for black-body recalibration during system integration. |
| Thermal gradient compensation | "CI" variant measures internal thermal gradients and applies real-time correction-reducing error from PCB hotspots or nearby heaters. |
| Configurable emissivity | User-adjustable ε = 0.1–1.0 via EEPROM address 0x04; no hardware change required for different surface materials (e.g., skin, metal, plastic). |
| Dual digital outputs | Simultaneous SMBus (high-precision, addressed reads) and PWM (low-pin-count, continuous streaming) enable flexible host interface options. |
| Thermal relay mode | PWM pin reconfigurable as comparator output with programmable To threshold-enables standalone thermostat or freeze-alert functionality without MCU intervention. |
| Medical accuracy option | ±0.2°C version available (not this part); current MLX90614ESF-DCI-000-SP delivers ±0.5°C standard accuracy optimized for HVAC and industrial use. |

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-TU | 3.0V supply (Bxx), no thermal gradient compensation (AA suffix), 35° FOV | Lacks CI's internal gradient correction; suited for stable-temperature PCB layouts only | Select when cost-sensitive and thermal environment is tightly controlled; not drop-in for gradient-prone placements. |
| AMG8833 | 8×8 thermal array (64 pixels), I²C interface, no built-in calibration, requires external optics | Provides spatial temperature mapping vs. single-point average; higher system complexity and calibration burden | Choose for presence detection or thermal imaging; avoid when single-zone accuracy, compact size, or factory calibration are mandatory. |
Compared with MLX90614ESF-DCI-000-SP, the MLX90614ESF-BAA-000-TU offers lower supply voltage but forfeits gradient immunity, while the AMG8833 trades simplicity and accuracy for pixel-level thermal data-making the MLX90614ESF-DCI-000-SP optimal for robust, calibrated single-point sensing in space-constrained designs.

FAQ
What is the operating temperature range of the MLX90614ESF-DCI-000-SP?
The MLX90614ESF-DCI-000-SP has an ambient operating temperature range of -40°C to +125°C and measures object temperatures from -70°C to +380°C. This wide range is validated per AEC-Q100 stress testing and enables deployment in under-hood automotive locations, industrial ovens, and medical devices without external thermal shielding.
Does the MLX90614ESF-DCI-000-SP require external calibration?
No, the MLX90614ESF-DCI-000-SP is fully factory-calibrated for both ambient and object temperature across its full operating range. Calibration coefficients, emissivity (default 1.0), and configuration settings are stored in on-chip EEPROM. Users may adjust emissivity or PWM range via SMBus writes-but black-body recalibration is unnecessary.
How does the "CI" suffix in MLX90614ESF-DCI-000-SP affect performance?
The "CI" suffix indicates integrated thermal gradient compensation. Unlike standard SF variants, the MLX90614ESF-DCI-000-SP internally measures thermal gradients across its TO-39 package and applies real-time correction to object temperature readings-reducing errors caused by nearby heat sources, PCB traces, or uneven ambient exposure.
Can the MLX90614ESF-DCI-000-SP operate from a 12V supply?
Yes-the MLX90614ESF-DCI-000-SP is an Axx-series device (5V-compatible), and the datasheet provides a verified external circuit (Section 5.5) using a Zener diode and resistor to safely operate from 8V–16V supplies. This avoids the need for a separate LDO and maintains SMBus compatibility with proper pull-up sizing.
What is the default communication interface for MLX90614ESF-DCI-000-SP at power-on?
The MLX90614ESF-DCI-000-SP powers up in SMBus mode by default (slave address 0x5A), with SDA and SCL pins active as open-drain bidirectional lines. PWM output is disabled until explicitly configured via EEPROM register 0x02. This ensures immediate interoperability with standard SMBus controllers without firmware initialization.
