Overview
The LM2903VQPWRQ1 is an automotive-grade dual differential voltage comparator manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2 V to 36 V, with the common-mode input voltage range including ground. The device features open-collector outputs and is designed for robust performance in harsh environments. It is qualified under AEC-Q100 standards and supports a wide operating temperature range from -40°C to +125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for long-term reliability
- Dual differential inputs with open-collector outputs for flexible interfacing
- Wide single-supply voltage operation from 2 V to 36 V
- Extended industrial temperature range suitable for engine and chassis applications
Applications
- Battery management systems
- Engine control units
- Body electronics monitoring
Procurement Notes
Verify the specific suffix 'V' against the official Texas Instruments datasheet to confirm package dimensions and thermal characteristics. Ensure the component meets AEC-Q100 Grade requirements for your target automotive application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.
Selection Notes
Select this component when dual comparators are required in space-constrained automotive designs. The TSSOP-8 package offers a compact footprint compared to larger SOIC options. Consider the open-collector output structure for level shifting or wired-OR configurations in system architectures.
Part Context
This device belongs to the LM2903-Q1 family of automotive dual comparators. It shares functional similarities with the commercial LM2903 but includes enhanced testing and reliability specifications mandated for automotive use. The 'Q1' suffix denotes automotive qualification, while 'V' indicates the TSSOP-8 package type.
Replacement Considerations
LM2903AVQPWRQ1: Higher precision variant within the same automotive family. LM2903BQDRQ1: Alternative package (SOIC-8) with similar automotive qualifications.
