Overview
The LM2903QPWRG4Q1 is an automotive-grade dual differential voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 30 V and supports single or dual power configurations. The device features open collector outputs with a typical sink current of 20 mA. Key electrical specifications include a maximum input offset voltage of 15 mV, an input bias current of 250 nA, and a propagation delay of 1.3 µs. It functions reliably across a temperature range of -40°C to +125°C and holds AEC-Q100 qualification.
Feature Summary
- Dual differential voltage comparison capability for signal threshold detection
- Open collector output architecture enabling flexible interfacing and wired-OR logic
- Automotive grade reliability certified under AEC-Q100 standards
- Wide single-supply operating voltage range supporting diverse system power rails
Applications
- Automotive sensor interface circuits
- Voltage monitoring and level detection systems
- Over-voltage and under-voltage protection schemes
- Window comparator applications in vehicle electronics
Procurement Notes
Verify the complete part number including suffixes to ensure correct package type and automotive qualification status. Confirm RoHS compliance and REACH status against current regulatory requirements. Check datasheet revisions for any changes in electrical characteristics or recommended operating conditions prior to final design integration.
Selection Notes
Select this component when automotive durability and wide supply voltage operation are required. Compare input offset voltage and propagation delay against application timing constraints. Ensure the open collector output configuration aligns with downstream logic requirements. Verify thermal performance within the specified ambient temperature range.
Part Context
This device belongs to the LM2903-Q1 family of dual comparators designed specifically for automotive environments. It shares functional similarities with non-automotive LM2903 variants but meets stricter quality and reliability standards. The TSSOP-8 package provides a compact solution for space-constrained printed circuit board layouts.
