Overview
The LM2901AVQPWR is a quad differential analog comparator manufactured by Texas Instruments, designed for automotive and industrial applications. It operates within a supply voltage range of 2 V to 36 V and features a low quiescent current of 2 mA. The device offers a propagation delay of 300 ns and an input offset voltage of 2 mV. It supports CMOS and TTL outputs and functions reliably across a temperature range of -40°C to +125°C. Packaged in a TSSOP-14 format, it meets AEC-Q100 qualification standards.
Feature Summary
- Automotive-grade reliability with AEC-Q100 qualification for harsh environments
- Quad differential architecture providing four independent comparison channels
- Low power consumption with a typical operating current of 2 mA
- High-speed response capability with a 300 ns propagation delay
Applications
- Hybrid electric vehicle (HEV) and electric vehicle (EV) powertrains
- Automotive body control modules
- Industrial process control systems
- Consumer appliance logic circuits
Procurement Notes
Verify the specific suffix 'G4' against official Texas Instruments documentation to confirm RoHS compliance and manufacturing status. Ensure the package type matches the required PCB footprint. Confirm that the automotive grade designation aligns with project requirements. Check for any recent product lifecycle notices or obsolescence warnings before finalizing procurement plans.
Selection Notes
Select this component when high precision and automotive durability are required. The 2 mV offset voltage ensures accurate threshold detection. The wide supply voltage range allows flexibility in system design. Consider the TSSOP-14 package for space-constrained layouts. Verify thermal performance under maximum load conditions.
Part Context
This part belongs to the LM2901AV series, which focuses on high-performance automotive comparators. It shares architectural similarities with other LM2901 variants but distinguishes itself through enhanced offset voltage specifications and automotive qualification. It serves as a robust alternative to standard commercial comparators in demanding vehicular applications.
Replacement Considerations
LM2901AVQPWRQ1 is a verified automotive-grade substitute with similar specifications. LM2901BIPWR offers a standard commercial alternative with different electrical characteristics. Verify pin compatibility and output drive capabilities before substitution.
