Product details

Overview

MLX90614ESF-ACC-000-TU from Melexis is a factory-calibrated, single-zone infrared thermometer IC in TO-39 metal can package, delivering ±0.5°C accuracy from 0°C to +50°C for both ambient and object temperature, with object range spanning -70°C to +380°C and SMBus-compatible digital interface. It integrates thermopile detector and signal conditioning ASSP for non-contact thermal sensing in automotive HVAC and medical-grade monitoring.

For engineers reviewing the MLX90614ESF-ACC-000-TU datasheet, pinout, applications, or equivalent options, key selection factors include its 5.0V supply compatibility, TO-39 package mechanical footprint, SMBus slave address 0x5A, PWM output configurability, and thermal gradient compensation capability in xCx variants (not applicable to this ACC variant).

Technical Context

The MLX90614ESF-ACC-000-TU 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 signal chain supports programmable FIR/IIR filtering and EEPROM-configurable emissivity (default 1.0), Ta/To ranges, and PWM output parameters.

It operates as an SMBus slave device with fixed 0x5A address (LSB configurable), supports 10–100 kHz clock frequency, and delivers 0.02°C resolution in SMBus mode. The device lacks sleep mode (excluded from Axx 5V variants) and uses internal RC oscillator for PWM timing (1.024 ms default period, ±10% stability).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5–5.5 V - compatible with standard 5V systems; no external regulator needed
Ambient Temp Range	-40°C to +85°C - matches ESF temperature grade; suitable for under-hood or cabin-mounted automotive use
Object Temp Range	-70°C to +380°C - enables broad industrial and medical applications without external scaling
Accuracy (Ta/To)	±0.5°C at 0°C…+50°C - guaranteed under isothermal conditions; requires thermal shielding in gradient-prone layouts
Output Interface	SMBus (default) + configurable PWM - dual-mode operation allows firmware-free analog-like readout or microcontroller-integrated digital polling
Resolution (SMBus)	0.02°C - sufficient for high-fidelity thermal feedback loops in HVAC and medical devices
Current Consumption	1.3–2.5 mA - enables direct integration into 5V-powered control modules without power budget concerns

Pinout & Package

MLX90614ESF-ACC-000-TU 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 to maintain EMC integrity and isothermal performance.

Pin/Terminal	Circuit Role	Design Meaning
1: SCL / Vz	SMBus clock input / 5.7 V zener clamp	Accepts 10–100 kHz SMBus clock; internal zener protects against overvoltage on 5V supply variants
2: SDA / PWM	SMBus data I/O or PWM output	Configurable dual-function pin; defaults to SMBus after POR; supports thermal relay mode via EEPROM
3: VDD	Positive supply	4.5–5.5 V input; no reverse polarity protection; requires local 100 nF decoupling
4: VSS	Ground reference	Single-point connection point for metal can; mandatory for thermal and EMC stability

Key Features

Feature	Design Value
Factory calibration	Delivers ready-to-use Ta and To values without user calibration; eliminates black-body setup and NIST traceability overhead
EEPROM programmability	Allows runtime configuration of emissivity (0.1–1.0), object/ambient temperature ranges, and PWM output mapping without hardware change
Thermal relay mode	Enables standalone thermostat function via PWM pin-user-programmable threshold triggers interrupt-capable wake-up on SMBus master
Optical filtering	Integrated 5.5–14 µm long-wave pass filter rejects visible and NIR radiation, ensuring immunity to sunlight and incandescent lighting
Multi-voltage adaptability	Supports 8–16 V operation using external components per datasheet Section 5.5-enables direct integration into automotive battery domains

FAQ

What is the operating temperature range for the MLX90614ESF-ACC-000-TU ambient sensor?

The MLX90614ESF-ACC-000-TU ambient temperature operating range is -40°C to +85°C, as defined by the 'E' temperature grade in its part number. This rating applies to the silicon die and package under isothermal conditions. Exceeding +85°C ambient may cause permanent damage or calibration drift, and the device is not rated for operation beyond this limit without derating or thermal management.

Does the MLX90614ESF-ACC-000-TU support sleep mode for low-power applications?

No, the MLX90614ESF-ACC-000-TU does not support sleep mode. Sleep mode is only available on the 3.0V-supply Bxx variants (e.g., MLX90614ESF-BCC-000-TU), which achieve 2–6 µA quiescent current. The ACC suffix denotes 5.0V operation, and per datasheet Note 6, sleep mode is explicitly excluded from all Axx versions including the MLX90614ESF-ACC-000-TU.

Can the MLX90614ESF-ACC-000-TU measure object temperatures below 0°C?

Yes, the MLX90614ESF-ACC-000-TU measures object temperatures from -70°C to +380°C. Its factory calibration covers this full range, and the SMBus interface reports raw To values with 0.02°C resolution. Accuracy remains ±0.5°C between 0°C and +50°C; outside that band, accuracy degrades per datasheet Figure 15 and must be validated per application conditions.

What is the default communication interface for the MLX90614ESF-ACC-000-TU at power-on?

The MLX90614ESF-ACC-000-TU defaults to SMBus interface at power-on reset (POR). The device powers up with SDA/SCL pins active as SMBus lines and responds to slave address 0x5A. PWM output mode must be explicitly enabled via EEPROM configuration (PWMCTRL register) or hardware pin strapping per datasheet Section 4.1.6.

Is the MLX90614ESF-ACC-000-TU pin-compatible with other MLX90614 variants in TO-39 package?

Yes, all MLX90614 variants with SF (TO-39) package-including MLX90614ESF-ACC-000-TU, MLX90614KSF-ACC-000-TU, and MLX90614ESF-BCC-000-TU-are mechanically and electrically pin-compatible. They share identical pinout, footprint, and soldering profile. Functional differences (supply voltage, ambient range, sleep mode) do not affect PCB layout or assembly.
