MLX75030CLQ-AAA-000-SP

Sensor And Detector Interfaces Overview

The MLX75030CLQ-AAA-000-SP 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. The component is housed in a QFN-24 package and supports an operating temperature range of 0°C to +70°C.

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
• Touch screen wake-up on proximity

Sensor And Detector Interfaces Procurement Notes

Verify the specific ordering suffix CLQ against the manufacturer's current documentation to confirm the exact temperature code (C) and packing form (Tube). Confirm that the component status remains NRND (Not Recommended for New Designs) before initiating procurement processes. Ensure all technical specifications align with the latest datasheet revision to avoid integration errors.

Sensor And Detector Interfaces Selection Notes

Select this model when the application requires operation within a 0°C to +70°C temperature range. Verify that the QFN-24 package dimensions fit the PCB layout constraints. Ensure the system power supply stays within the 3.0V to 3.6V range. Consider the 6mA active current consumption for battery life calculations if applicable.

Sensor And Detector Interfaces Part Context

This part belongs to the MLX75030 series from Melexis, which provides universal active light sensor interfaces. The 'C' designation indicates the commercial temperature grade (0°C to +70°C), distinguishing it from the 'R' variant which supports automotive-grade temperatures (-40°C to +105°C). Both variants share identical functional capabilities and pinouts.

Sensor And Detector Interfaces Replacement Considerations

The MLX75030RLW-BAA-000-SP is a direct functional substitute with an extended industrial/automotive temperature range (-40°C to +105°C). Verify that the higher temperature rating does not introduce compatibility issues with existing thermal management designs.
