MLX75030CLQ-AAA-000-TU

Sensor And Detector Interfaces Overview

The MLX75030CLQ-AAA-000-TU is a universal active light sensor interface IC designed for robust multi-channel optical sensing. It features two independent active light measurement channels with integrated DC light cancellation and two logarithmic ambient light channels. The device operates on a 3.0V to 3.6V supply, drawing 6mA in active mode. It utilizes an SPI digital interface and includes a 16-bit ADC, temperature sensor, and watchdog timer. Packaged in a QFN-24 (4x4 mm) SMD format, it supports tube packing.

Sensor And Detector Interfaces Feature Summary

• Integrated hardware-level ambient light suppression for virtually background-light-independent active detection
• Dual independent active light channels with high input capacitance tolerance
• Two logarithmic ambient light channels for wide dynamic range measurement
• Comprehensive diagnostic functions including window watchdog timer and error monitoring

Sensor And Detector Interfaces Applications

• Optical proximity sensing and display dimming
• Touch-less gesture recognition systems
• Driver/passenger discrimination in automotive HMI
• Touch screen wake-up triggered by proximity

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix TU indicates tube packaging rather than reel. Confirm the C temperature code corresponds to the 0°C to 70°C operating range required for your application environment. Ensure the BAA-000 option code matches the intended design revision before finalizing procurement orders.

Sensor And Detector Interfaces Selection Notes

Select this component when dual-channel active reflection and ambient light measurement are required simultaneously. The C variant is suitable for commercial environments within 0°C to 70°C. Consider the R variant if operation down to -40°C is necessary. Verify that the QFN-24 package footprint fits the PCB layout constraints.

Sensor And Detector Interfaces Part Context

This part belongs to the MLX75030 series of Universal ActiveLight Sensor Interfaces from Melexis. It is specifically engineered for Human-Machine Interfaces requiring proximity or gesture detection in varying background lighting conditions. The device integrates analog front-end processing with digital control logic to simplify system design.

Sensor And Detector Interfaces Replacement Considerations

Check for MLX75030RLW-BAA-000-SP if extended temperature range (-40°C to 105°C) is needed. Verify pin compatibility and register mapping if substituting with other Melexis sensor interfaces. No direct cross-brand replacements are documented.
