LM2901VQPWR

Overview

The LM2901VQPWR is a quad differential comparator from Texas Instruments, housed in a 14-pin TSSOP package. It operates on a single supply voltage ranging from 2 V to 36 V or dual supplies of ±1 V to ±18 V. The device features an open-collector output compatible with CMOS and TTL logic. Key electrical parameters include a maximum input offset voltage of 7 mV, an input bias current of 250 nA, and a typical response time of 300 ns. It supports a quiescent supply current of 2.5 mA and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Quad differential architecture providing four independent comparison channels
• Wide single-supply operation capability up to 36 V
• Open-collector outputs ensuring compatibility with various logic families

Applications

• Automotive electronic systems
• Industrial control circuits
• Consumer appliance logic interfaces

Procurement Notes

Verify the specific suffix 'G4' against the datasheet to confirm lead-free status and RoHS compliance details. Ensure the ordering part number matches the exact package variant required for your PCB footprint. Confirm that the automotive qualification level meets your system's reliability standards before finalizing procurement.

Selection Notes

Select this component when multiple independent voltage comparisons are needed in a space-constrained design. The wide supply voltage range allows flexibility in power distribution networks. Consider the open-collector output requirement for pull-up resistor implementation in the circuit design phase.

Part Context

This device belongs to the LM2901 family of low-power analog comparators. It serves as a high-density alternative to discrete comparator solutions. The TSSOP-14 packaging facilitates automated surface-mount assembly processes while maintaining thermal performance suitable for industrial environments.

Replacement Considerations

Direct substitutes include LM2901AVQPWR and LM2901VQDR. Verify pinout compatibility and electrical parameter tolerances such as input offset voltage and response time before swapping components.
