LM2903AVQPWRG4Q1

Overview

The LM2903AVQPWRG4Q1 is a dual differential voltage comparator designed for automotive applications, certified under AEC-Q100 standards. It operates within a supply voltage range of 2 V to 32 V and features an open collector output type. The device exhibits a typical response time of 1.3 µs and maintains a maximum input offset voltage of 4 mV. Operating power current ranges from 1 mA to 2.5 mA, with an input bias current of 250 nA. It functions reliably across a temperature range of -40°C to +125°C and is housed in an 8-pin TSSOP package.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliability in vehicle electronics.
• Dual differential configuration providing two independent comparison channels in a compact surface-mount package.
• Open collector output architecture enabling flexible interfacing with various logic families and pull-up configurations.

Applications

• Automotive sensor signal conditioning
• Voltage level detection circuits
• Window comparator implementations

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status according to the manufacturer's latest documentation. Confirm that the Q1 designation aligns with required automotive reliability standards for the target application environment. Ensure the TSSOP-8 footprint matches the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when dual-channel comparison is required in space-constrained automotive designs. The wide supply voltage range supports direct interfacing with various sensor types without additional level shifting. Consider the 1.3 µs propagation delay for timing-sensitive applications where faster switching speeds are not critical.

Part Context

This part belongs to the LM2903-Q1 family of dual comparators specifically engineered for automotive environments. It shares functional similarities with standard industrial comparators but includes enhanced testing and quality controls mandated by automotive industry requirements. The device serves as a robust solution for monitoring voltage thresholds in complex electronic control units.

Replacement Considerations

LM2903AVQPWRQ1 is a verified substitute offering identical electrical characteristics and automotive qualification in the same TSSOP-8 package.
