Overview
The LM2903BTQDRQ1 is an automotive-grade dual differential comparator from Texas Instruments, part of the LM2903B-Q1 family. It operates on a single or dual supply ranging from 2V to 36V within an ambient temperature range of -40°C to +125°C. The device features low quiescent current (typically 200µA per comparator), low input bias current (3.5nA typical), and low input offset voltage (±0.37mV typical). It provides improved ESD protection with 2kV HBM rating and offers a propagation delay of 1µs typical. Packaged in SOIC-8.
Feature Summary
- Qualified for automotive applications with AEC-Q100 Grade 1 certification
- Features low supply current independent of supply voltage
- Includes dedicated ESD protections for improved robustness
- Open-drain output compatible with TTL, MOS, and CMOS logic
Applications
- HEV/EV and power train systems
- Infotainment and cluster modules
- Body control modules
Procurement Notes
Verify the specific suffix 'D' corresponds to the SOIC-8 package and confirm the 'B' variant specifications against the official datasheet. Ensure the component meets the required AEC-Q100 Grade 1 temperature range and functional safety documentation requirements for your specific design implementation.
Selection Notes
Select this component when high voltage tolerance up to 36V and low power consumption are critical. The LM2903B-Q1 series offers superior offset voltage and ESD performance compared to standard LM2903-Q1 variants. Consider the open-drain output requirement for level shifting applications.
Part Context
This device belongs to the LM2903-Q1 family of dual comparators designed for cost-sensitive automotive applications. The 'B' designation indicates enhanced electrical characteristics, including lower offset voltage and higher ESD immunity, while maintaining drop-in replacement compatibility with previous generations.
