LM2901VQPWRG4

Overview

The LM2901VQPWRG4 is a quad differential comparator from Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It operates on a single supply voltage ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features an open-collector output type and is housed in a 14-TSSOP package. Key electrical parameters include a maximum input offset voltage of 7 mV at 5 V and a maximum input bias current of 0.25 µA at 5 V. The quiescent current is typically 2.5 mA, with a typical response time of 1.3 µs. It supports a maximum output current of 20 mA per channel and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards for robust performance in vehicle environments.
• Quad differential architecture provides four independent comparison channels within a compact surface-mount package.
• Wide single-supply operation allows compatibility with standard low-voltage logic and power systems.

Applications

• Automotive sensor signal conditioning
• Voltage monitoring circuits
• Over-voltage protection systems

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-14 package dimensions match PCB footprint requirements. Ensure the AEC-Q100 qualification aligns with target automotive application stress tests. Check for any recent PCN updates regarding packaging or material changes before finalizing procurement orders.

Selection Notes

Select this component when high reliability in automotive environments is required alongside low-power consumption. The wide supply voltage range simplifies design across various automotive bus architectures. Consider the open-collector output for flexible interfacing with different logic families. Verify that the 1.3 µs response time meets the speed requirements of the specific application circuit.

Part Context

This part belongs to the LM2901 family of quad differential comparators manufactured by Texas Instruments. It is specifically engineered for automotive use, distinguishing it from commercial variants through enhanced durability and qualification standards. The device serves as a critical interface between analog sensors and digital control units in modern vehicles.

Replacement Considerations

LM2901VQDR is a compatible non-automotive grade alternative with similar electrical characteristics but lacks AEC-Q100 certification. Designers requiring automotive qualification must verify that substitute parts meet specific industry reliability standards.
