MLX75030RLQ-AAA-000-RE

Sensor And Detector Interfaces Overview

The MLX75030RLQ-AAA-000-RE 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, and supports an SPI digital interface. It includes an integrated 16-bit ADC, temperature sensor, and watchdog timer within a QFN-24 package.

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 and monitoring functions for high safety design

Sensor And Detector Interfaces Applications

• Optical proximity sensing and display dimming
• Touch-less gesture recognition
• Driver/passenger discrimination systems
• Touch screen wake-up on proximity

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix RE indicates reel packing versus TU for tube. Confirm the temperature code R corresponds to the -40°C to +105°C operating range required for your application environment. Ensure the QFN-24 wettable flank package is compatible with your PCB assembly process.

Sensor And Detector Interfaces Selection Notes

Select this component when dual-channel active reflection and ambient light measurement are required simultaneously. The integrated LED drivers simplify external circuitry. Consider the C version if only 0°C to 70°C operation is needed. Verify SPI compatibility with the host microcontroller before integration.

Sensor And Detector Interfaces Part Context

This part belongs to the MLX75030 Universal ActiveLight Sensor Interface family from Melexis. It is specifically engineered for human-machine interfaces requiring proximity or gesture detection in varying background lighting conditions. The RLQ variant denotes the automotive-grade temperature range and reel packaging format.

Sensor And Detector Interfaces Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should verify pin-to-pin compatibility and electrical specifications if considering alternative sensors from other manufacturers.
