Overview
The LM2903EPWRQ1 is an automotive-grade dual differential voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 32 V and features open collector outputs. The device exhibits a typical response time of 1.3 µs and draws a quiescent current between 1 mA and 2.5 mA. Input characteristics include a maximum input offset voltage of 4 mV and an input bias current of 250 nA. It is qualified under AEC-Q100 standards for Grade 0 and Grade 1 applications, supporting operation temperatures from -40°C to +125°C or +150°C depending on specific grading.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for Grade 0 and Grade 1 reliability requirements.
- Dual differential configuration designed for single or dual power supply operations across wide voltage ranges.
- Open collector output architecture enabling flexible interfacing and wired-OR logic capabilities.
Applications
- Automotive electronic control units requiring high-voltage signal monitoring
- Over-voltage and under-voltage protection circuits in vehicle power systems
- Window comparator implementations for battery management systems
Procurement Notes
Verify the specific AEC-Q100 grade (Grade 0 or Grade 1) required for your application, as temperature ratings may vary between grades. Confirm the operating temperature range specifications against your system's thermal constraints. Ensure the TSSOP-8 package dimensions align with your PCB layout requirements. Cross-reference the datasheet revision to confirm electrical parameters match your design specifications.
Selection Notes
Select this component when automotive reliability and high-voltage tolerance are critical. The dual-channel design reduces board space compared to single comparators. Consider the 1.3 µs response time for speed-sensitive applications. Verify that the open collector output suits your pull-up resistor configuration. Evaluate the 32 V maximum supply limit against your system's peak voltage conditions.
Part Context
This part belongs to the LM2903 family of dual differential comparators. It shares functional similarities with the LM2903AVQPWRG4Q1 but differs in automotive grading and specific electrical tolerances. The EP suffix typically denotes an extended temperature range or specific automotive grade variant within the TI portfolio. It serves as a robust alternative to standard commercial comparators in harsh environments.
Replacement Considerations
LM2903AVQPWRG4Q1 is a related automotive-grade dual differential comparator. Verify if the specific AEC-Q100 grade and temperature range of the substitute meet your design requirements before implementation.
