Overview
The LM2903QPWRQ1 is an automotive-grade dual differential voltage comparator manufactured by Texas Instruments. It operates from a single supply of 2 V to 30 V or dual supplies of ±1 V to ±15 V. The device features open-collector outputs and a typical response time of 1.3 µs. Input offset voltage is typically 15 mV, with input bias current at 250 nA. It functions within a temperature range of -40°C to +125°C and is housed in an 8-pin TSSOP package.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for long-term reliability
- Dual differential architecture enabling independent signal comparison on two channels
- Open-collector output configuration allowing flexible interfacing with various logic families
Applications
- Automotive electronic control units requiring robust voltage monitoring
- Over-voltage and under-voltage protection circuits in vehicle power systems
- Window comparator implementations for sensor signal validation
Procurement Notes
Verify the specific suffix G4 against official Texas Instruments documentation to confirm manufacturing lot details and compliance status. Ensure the procurement channel provides valid traceability records for automotive components. Confirm that the delivered package matches the specified TSSOP-8 form factor and that all relevant RoHS directives are met as per the latest datasheet revision.
Selection Notes
Select this component when designing for automotive environments necessitating AEC-Q100 certification. The wide supply voltage range supports direct integration into 12V and 24V automotive networks without level shifting. The open-collector output simplifies interface design with microcontrollers and other digital logic levels commonly found in vehicle architectures.
Part Context
This part belongs to the LM2903-Q1 family of dual comparators designed specifically for automotive applications. It shares functional similarities with the commercial LM2903 but meets stricter automotive reliability and temperature requirements. The Q1 designation indicates its suitability for use in safety-critical and high-reliability vehicle subsystems where consistent performance over extended lifespans is mandatory.
Replacement Considerations
LM2903QPWRG4Q1 is a confirmed substitute within the same product family.
