Product details
Overview
MLX75030CLQ-AAA-000-TU from Melexis is a universal active light sensor interface IC designed for dual-channel modulated IR proximity and ambient light sensing in automotive and industrial HMIs. It integrates two independent ActiveLight channels (A/B) with hardware-level DC sunlight suppression, two logarithmic ambient light channels (C/D), a 16-bit ADC, temperature sensor, SPI interface, and LED drivers - enabling robust optical sensing under >900 µA DC background illumination in touchless gesture and driver discrimination systems.
For engineers reviewing the MLX75030CLQ-AAA-000-TU datasheet, pinout, applications, or equivalent options, this device delivers verified simultaneous active/ambient measurement, programmable DC compensation across five segments, 45.7–109.4 kHz carrier frequency selection, and QFN24 4×4 mm wettable flank packaging for high-reliability optical module integration.
Technical Context
The MLX75030CLQ-AAA-000-TU implements two parallel analog signal chains: ActiveLight channels A/B use transimpedance amplifiers with integrated DC cancellation circuitry to reject up to 900 µA of ambient photocurrent while measuring modulated NIR signals; ambient channels C/D employ logarithmic current-to-voltage conversion with 0.01–1040 µA (C) and 0.5–20 nA (D) input ranges. Each channel feeds into a shared 16-bit ADC with configurable averaging (13-bit effective resolution).
Its digital subsystem includes an SPI interface (0.5–5 MHz), window watchdog timer (140 ms init window), programmable sleep/standby modes (50 µA / 500 µA quiescent), and diagnostic registers (Err2–Err6) monitoring TIA output, SC filter voltage, DAC/sense mismatch, RCO stability, and regulator startup - all coordinated by on-chip control logic without external microcontroller intervention.

Equivalent & Alternatives
The following parts are listed as comparable options for similar active/ambient optical sensing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VEML6040 | Single-channel ambient light sensor only; no ActiveLight, LED drivers, or DC cancellation circuitry. | Limited to display dimming; cannot perform proximity or gesture functions. | Select when only ambient light measurement is needed and cost is primary constraint. |
| ams TMD2755 | Integrated proximity + ambient sensor with 1-channel ActiveLight; lacks dual ActiveLight channels and programmable DC compensation segments. | Suitable for basic proximity but not robust under high DC background or multi-gesture scenarios. | Choose for compact single-LED designs where sunlight rejection <500 µA suffices. |
Compared with VEML6040 and TMD2755, the MLX75030CLQ-AAA-000-TU uniquely provides dual independent ActiveLight channels with hardware-level DC cancellation up to 900 µA, two logarithmic ambient channels, and integrated LED drivers - making it the only solution qualified for ASIL-B automotive proximity HMI requiring simultaneous active/ambient measurement and sunlight immunity.

FAQ
What is the operating temperature range of the MLX75030CLQ-AAA-000-TU?
The MLX75030CLQ-AAA-000-TU is rated for −40°C to +105°C (Grade R), matching AEC-Q100 automotive requirements. This range is confirmed in the Absolute Maximum Ratings table (Tj ≤ 150°C) and General Electrical Specifications, where all parameters - including ActiveLight DC compensation, ambient channel linearity, and temperature sensor accuracy - are guaranteed across this full interval.
Does the MLX75030CLQ-AAA-000-TU support simultaneous sampling of all four channels?
Yes, the MLX75030CLQ-AAA-000-TU supports true simultaneous operation: ActiveLight channels A and B measure modulated IR signals concurrently, while ambient channels C and D perform independent logarithmic photocurrent conversion. The internal control logic sequences ADC conversions without inter-channel crosstalk, enabling synchronized multi-modal optical profiling essential for gesture discrimination.
How does the DC light cancellation work in the MLX75030CLQ-AAA-000-TU?
The MLX75030CLQ-AAA-000-TU implements hardware-level DC cancellation using a five-segment programmable compensation algorithm. It measures ambient DC photocurrent on each ActiveLight channel, then injects proportional counter-current via integrated DACs to nullify background contribution before TIA amplification - verified to suppress up to 900 µA DC light while preserving AC signal integrity.
What package type and footprint does the MLX75030CLQ-AAA-000-TU use?
The MLX75030CLQ-AAA-000-TU uses a QFN24 4×4 mm package with wettable flanks (package code LW), as specified in the Ordering Information section. Pin layout matches Figure 1 in the datasheet, with exposed thermal pad connected to GNDA; footprint complies with JEDEC MO-220 standards and supports reflow soldering per Melexis' manufacturability guidelines.
Can the MLX75030CLQ-AAA-000-TU drive LEDs directly?
No, the MLX75030CLQ-AAA-000-TU does not drive LEDs directly. Its Drive LED A and Drive LED B pins are analog gate-drive outputs designed to control external N-channel FETs (e.g., DMN3025LSD) that switch high-current NIR LEDs. The IC provides precise timing, current regulation feedback (via Shunt R−/GND), and diagnostics - but requires external FETs for >100 mA LED currents.
