LM2901BWRTERQ1

Overview

The LM2901BWRTERQ1 is a quadruple automotive comparator from Texas Instruments, housed in a 16-pin WQFN package. It operates on a single or dual supply ranging from 2V to 36V with an ambient temperature range of -40°C to +125°C. The device features a typical quiescent current of 800µA and a maximum input offset voltage of ±5.5mV across the full temperature range. Propagation delay is specified at 1000ns for small-scale signals and 300ns for TTL inputs. It includes AEC-Q100 Grade 1 qualification and enhanced 2kV HBM ESD protection.

Feature Summary

• Enhanced electrostatic discharge (ESD) performance with dedicated protections on all pins for improved robustness.
• Low power consumption characterized by supply current independent of the supply voltage level.
• High precision achieved through low input bias and offset currents alongside minimal input offset voltage.
• Wide common-mode input voltage range that includes ground potential.

Applications

• HEV/EV and power train systems
• Infotainment and cluster modules
• Body control modules

Procurement Notes

Verify the specific suffix 'RTER' corresponds to the WQFN-16 package with an exposed thermal pad during procurement. Confirm the component meets AEC-Q100 Grade 1 requirements for the intended automotive environment. Ensure the design accounts for the open-drain output configuration requiring external pull-up resistors for proper logic high levels.

Selection Notes

Select this component when drop-in replacement convenience and cost sensitivity are priorities within the LM2901x-Q1 family. Choose this variant over standard versions if higher supply voltage capability up to 36V and improved ESD ratings are required. Consider the WQFN package for applications needing compact board space with thermal dissipation capabilities via the exposed pad.

Part Context

This part belongs to the LM2901-Q1 family, representing the next-generation version of the industry-standard LM2901x-Q1 comparators. It offers improved electrical characteristics including lower offset voltage, lower propagation delay, and reduced supply current compared to previous iterations while maintaining functional compatibility.
