Overview
The LM2903BQPWRQ1 is an automotive-grade dual differential voltage comparator manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 36 V and features open collector outputs. The device exhibits a propagation delay of 300 ns and a response time of 1 µs. Input offset voltage is specified at 4 mV, with input bias current at 25 nA. Operating temperature spans from -40°C to +125°C. It is housed in an 8-pin TSSOP package.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Dual differential configuration enabling independent signal comparison
- Open collector output architecture supporting flexible interfacing
Applications
- Automotive electronic control units
- Voltage monitoring circuits
- Over-voltage protection systems
Procurement Notes
Verify the specific suffix 'B' indicates the B-grade performance variant regarding offset voltage and bias current specifications compared to standard grades. Confirm the 'Q1' suffix denotes automotive qualification status. Ensure the 'PWR' suffix matches the required TSSOP-8 package dimensions for PCB layout compatibility. Cross-reference the manufacturer datasheet revision date to ensure technical data currency.
Selection Notes
Select this component when automotive reliability is mandatory alongside low power consumption requirements. The B-grade specification offers tighter input offset voltage tolerances suitable for precision sensing applications. The wide supply voltage range accommodates various automotive bus architectures without additional level shifting components.
Part Context
This part belongs to the LM2903-Q1 family of dual comparators designed specifically for automotive environments. It shares functional similarities with the non-automotive LM2903 but includes enhanced testing and documentation for automotive deployment. The family provides a cost-effective solution for general-purpose comparison tasks in vehicle electronics.
Replacement Considerations
LM2903QPWRQ1 serves as a verified substitute within the same product family, offering identical functionality and packaging.
