Overview
The LM2903QPWRRB is an automotive-grade dual differential comparator from the LM2903-Q1 family, manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2V to 30V or dual supplies within the same differential limit. The device features open-drain outputs and is qualified under AEC-Q100 Grade 1 standards for operation in ambient temperatures between -40°C and +125°C. It utilizes a TSSOP-8 package with dimensions of 3.00mm x 4.40mm. Key electrical characteristics include a typical response time of 1.3µs, a maximum input offset voltage of ±15mV over temperature, and a quiescent current of 1mA to 2.5mA.
Feature Summary
- Qualified for automotive applications meeting AEC-Q100 Grade 1 specifications
- Operates with wide supply voltage range from 2V to 30V
- Features open-drain outputs compatible with TTL, MOS, and CMOS logic
- Common-mode input voltage range includes ground potential
Applications
- Automotive HEV/EV and power train systems
- Infotainment and instrument cluster circuits
- Body control module applications
Procurement Notes
Verify that the specific suffix 'RB' corresponds to the intended packaging and temperature testing options as defined in the manufacturer's orderable addendum. Confirm the device meets the required AEC-Q100 Grade 1 qualification for your specific automotive environment. Ensure the TSSOP-8 thermal management aligns with your system design constraints given the junction-to-ambient resistance values.
Selection Notes
Select this component when an AEC-Q100 qualified dual comparator is required for automotive environments operating up to 125°C. It is suitable for designs needing a wide supply voltage range up to 30V and open-drain output flexibility. Consider the standard LM2903-Q1 performance metrics if lower cost is prioritized over the specific 'B' version enhancements found in other family members.
Part Context
This part belongs to the LM2903-Q1 family of dual differential comparators designed for robust automotive use. The family includes variants like the LM2903E-Q1 for extended temperature ranges and the LM2903B-Q1 for improved ESD and offset performance. All devices share the core architecture of PNP darlington pair inputs and open-drain outputs, ensuring compatibility across various automotive electronic control units.
