LM2901VQPWRQ1

Overview

The LM2901VQPWRQ1 is a quad differential analog comparator from Texas Instruments, designed for automotive applications. It operates on a single or dual power supply ranging from 2 V to 36 V. The device features an open-collector output compatible with TTL, MOS, and CMOS logic families. Key electrical specifications include a maximum input offset voltage of 7 mV at 5 V, a typical quiescent current of 2.5 mA, and a propagation delay of 300 ns. It is housed in a 14-TSSOP package and supports an operating temperature range from -40°C to +125°C.

Feature Summary

• AEC-Q100 qualified for automotive environments with specified temperature grades and ESD classification levels.
• Supports wide single-supply (2 V to 36 V) and dual-supply operation with low power consumption independent of supply voltage.
• Open-collector outputs allow wired-AND functionality and compatibility with various digital logic families.

Applications

• Automotive body control modules
• HEV/EV powertrain systems
• Industrial sensor signal conditioning

Procurement Notes

Verify the specific suffix 'G4' if referencing the alternate part number LM2901VQPWRG4Q1, as it may indicate packaging or revision differences. Confirm the 14-TSSOP package dimensions against your PCB footprint requirements. Ensure the open-collector output configuration aligns with your pull-up resistor design for the target logic voltage level.

Selection Notes

Select this component when high channel density is required within a compact TSSOP footprint. The 7 mV max offset voltage provides sufficient accuracy for general-purpose comparisons where ultra-high precision is not critical. The wide supply voltage range makes it suitable for direct interfacing with various automotive and industrial power rails without additional level shifting.

Part Context

This device belongs to the LM2901 family of quad comparators. It shares functional similarities with the LM2901AVQPWRQ1 but differs in input offset voltage specifications, with the 'V' variant offering a higher max offset of 7 mV compared to the 'AV' variant's 2 mV. Both are AEC-Q100 qualified and share similar pinouts and output structures.

Replacement Considerations

LM2901VQPWRG4Q1 is a verified equivalent part number for the LM2901VQPWRQ1, typically indicating a specific manufacturing revision or packaging update. Other family members like LM2901AVQPWRQ1 offer lower offset voltages but may have different thermal or electrical characteristics requiring circuit re-evaluation.
