Overview
The LM2903VQPWRG4Q1 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 a maximum operating temperature of +125°C and a minimum of -40°C. The device features open collector and open drain outputs, drawing a typical supply current between 1 mA and 2.5 mA. Key electrical specifications include a maximum input offset voltage of 15 mV, an input bias current of 250 nA, and an input offset current of 50 nA. It has a response time of 1.3 µs and is housed in an 8-pin TSSOP package.
Feature Summary
- Dual differential voltage comparison capability designed for wide single-supply operation
- Automotive qualification compliant with AEC-Q100 standards for reliability
- Flexible output configuration supporting both open collector and open drain modes
Applications
- Automotive electronic control units requiring signal threshold detection
- Over-voltage and under-voltage monitoring circuits in vehicle power systems
- Window comparator applications for safety-critical sensor inputs
Procurement Notes
Verify the complete part number including suffixes such as G4 and Q1 to ensure correct packaging, temperature grade, and automotive qualification status. Confirm that the TSSOP-8 package matches your PCB footprint requirements. Cross-reference the specific revision level against the manufacturer's latest datasheet to account for any potential design or marking changes documented in recent product change notifications.
Selection Notes
Select this component when dual independent comparators are required within a compact surface-mount form factor for automotive environments. The wide supply voltage range accommodates various automotive battery architectures without additional regulation. Ensure the 1.3 µs propagation delay meets the timing constraints of your application, as faster alternatives exist within the family but may differ in offset voltage characteristics.
Part Context
This device belongs to the LM2903-Q1 series, which extends the standard LM2903 functionality to meet automotive quality requirements. It shares architectural similarities with other members like the LM2903AVQPWRQ1 but differs in specific electrical parameters such as input offset voltage and package type. The series is designed to replace legacy discrete comparator solutions in modern automotive designs.
