LM2901AVQPWRQ1

Overview

The LM2901AVQPWRQ1 is a quad differential comparator designed for automotive applications, featuring AEC-Q100 qualification. It operates on a single or dual power supply ranging from 2 V to 36 V. Key electrical parameters include a typical supply current of 0.8 mA, input bias current of 25 nA, and input offset voltage of 2 mV. The device offers a propagation delay of 300 ns and supports rail-to-rail output compatibility with TTL, MOS, and CMOS logic families.

Feature Summary

• Automotive-grade reliability with AEC-Q100 certification for temperature grade 1 operation.
• Low power consumption with supply current independent of the supply voltage.
• Wide common-mode input voltage range that includes ground potential.
• Output compatibility with standard digital logic families including TTL, MOS, and CMOS.

Applications

• Hybrid electric vehicle (HEV) and electric vehicle (EV) powertrain systems
• Automotive information entertainment and instrument cluster circuits
• Body control module signal processing

Procurement Notes

Verify the specific suffix 'G4' if present in ordering codes, as it denotes lead-free status and RoHS compliance but does not alter functional performance. Confirm package type TSSOP-14 availability matches design requirements. Ensure component authenticity through authorized distribution channels to maintain AEC-Q100 integrity. Check datasheet revisions for any pinout or electrical characteristic updates prior to final implementation.

Selection Notes

Select this component when automotive durability and low quiescent current are critical. The wide supply voltage range suits direct battery monitoring in harsh environments. Rail-to-rail outputs simplify interface design with downstream digital logic. Verify thermal management needs for TSSOP-14 packaging under maximum load conditions.

Part Context

Part of the LM2901AV family of quad differential comparators manufactured by Texas Instruments. Designed specifically for high-reliability automotive electronics requiring robust performance across extended temperature ranges. Shares architectural similarities with non-automotive LM2901 variants but includes enhanced testing for automotive quality standards.

Replacement Considerations

LM2901AVQPWRQ1 serves as the qualified automotive version of the commercial LM2901AVQPWR. Direct substitution requires verifying that the commercial variant meets the required operating temperature range and reliability standards for the specific application environment.
