Overview
The LM2903YQ3T is a low-power dual voltage comparator manufactured by STMicroelectronics, housed in an 8-lead DFN 2x2 mm package with wettable flanks. It operates from a single supply of +2 V to +36 V or dual supplies of ±1 V to ±18 V. The device features a very low supply current of 0.4 mA independent of voltage and includes input common-mode range extending to the negative rail. Electrical specifications include a maximum input offset voltage of 15 mV, a typical response time of 500 ns for large signals, and an output sink current capability of 16 mA.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards
- DFN 2x2 mm package featuring wettable flanks for enhanced inspection reliability
- Input common-mode voltage range extends to the negative power supply rail
- Outputs compatible with TTL, DTL, ECL, MOS, and CMOS logic families
Applications
- Zero crossing detection circuits
- Window comparator configurations
- Transducer amplification
- Time delay generation
Procurement Notes
Verify that the specific order code matches the required automotive grade (AEC-Q100) and the DFN 2x2 mm package variant with wettable flanks. Confirm the manufacturer source is STMicroelectronics to ensure compliance with the specified electrical characteristics and thermal resistance values. Ensure the component meets RoHS directives as indicated in the datasheet.
Selection Notes
Select this component when a compact surface-mount solution is required for automotive applications. The DFN 2x2 mm footprint offers space savings compared to SO8 or TSSOP8 packages. The inclusion of wettable flanks facilitates automated optical inspection. Consider the 500 ns response time and 16 mA output drive capability against system timing and load requirements.
Part Context
This part belongs to the LM2903 family of low-power dual voltage comparators. While other variants like the LM2903W offer higher ESD performance and the LM2903H supports temperatures up to 150 °C, the LM2903YQ3T specifically targets automotive environments requiring AEC-Q100 certification within a small form factor.
Replacement Considerations
LM2903Q3T: Identical functional specifications but utilizes a different DFN 2x2 mm manufacturing process without wettable flanks.
