LM2901VQPWRG4Q1

Overview

The LM2901VQPWRG4Q1 is a quad differential analog comparator designed for automotive applications, certified under AEC-Q100 standards. It operates within a supply voltage range of 2 V to 36 V and features an open-collector output type compatible with CMOS and TTL logic families. The device includes four independent channels housed in a 14-TSSOP surface-mount package. Key electrical specifications include a maximum input offset voltage of 7 mV at 5 V, a maximum input bias current of 0.25 µA at 5 V, and a typical output current capability of 20 mA. It functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for reliability in vehicle environments.
• Quad differential architecture providing four independent comparison channels in a single integrated circuit.
• Wide single-supply operation capability supporting voltages from 2 V up to 36 V.
• Open-collector output interface ensuring compatibility with various digital logic families.

Applications

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

Procurement Notes

Verify the specific suffix G4Q1 confirms the automotive grade and TSSOP-14 packaging configuration. Ensure the ordering part number matches the required RoHS compliance status and moisture sensitivity level. Confirm that the supplier provides documentation verifying the AEC-Q100 certification for the intended automotive application context.

Selection Notes

Select this component when high channel density and automotive reliability are required. The open-collector output necessitates external pull-up resistors for proper logic level generation. Consider the 7 mV input offset voltage specification for precision requirements. Verify that the 20 mA output drive current meets the load requirements of the downstream circuitry without exceeding absolute maximum ratings.

Part Context

This device belongs to the LM2901 family of quad comparators manufactured by Texas Instruments. The 'V' designation typically indicates a specific performance grade or variant within the series, while 'Q1' denotes automotive qualification. It serves as a specialized version of standard commercial comparators, optimized for the thermal and reliability demands of automotive electronics.

Replacement Considerations

Direct substitutes may include other AEC-Q100 qualified quad comparators from Texas Instruments such as the LM2901B series variants, provided they match the pinout and electrical characteristics. Cross-manufacturer replacements require careful verification of input offset voltage, propagation delay, and output drive capabilities to ensure functional equivalence.
