LM2901PWR

Overview

The LM2901PWR is a quad voltage comparator from Texas Instruments housed in a 14-pin TSSOP package. It operates on a single supply of 2V to 36V or dual supplies of ±1V to ±18V. Key electrical parameters include a typical response time of 1.3μs, input bias current of 25nA, and input offset voltage of 7mV. The device features open-collector outputs compatible with TTL, MOS, and CMOS logic families.

Feature Summary

• Quad differential voltage comparators integrated into a single low-power package
• Wide single and dual power supply operating ranges for flexible system integration
• Open-collector outputs allowing wired-AND connection capabilities
• Low input bias and offset currents ensuring high precision signal comparison

Applications

• Battery-powered systems requiring low quiescent current
• On-temperature sensing circuits
• Logic level translation between different voltage domains
• Simple analog-to-digital conversion interfaces

Procurement Notes

Verify the specific suffix against the manufacturer's datasheet to confirm exact testing limits and automotive qualification status. Ensure the ordering part number matches the required package style and tape-and-reel specifications. Cross-reference the component marking code with official documentation to prevent counterfeit substitution during assembly.

Selection Notes

Select this component when multiple independent comparisons are needed within space-constrained designs. The TSSOP package offers a compact footprint suitable for surface-mount applications. Consider the open-collector output structure if wired-AND logic functionality is required without additional external components.

Part Context

This device belongs to the LM2901 family of quad comparators, designed as a low-power alternative to standard general-purpose comparators. It shares functional similarities with the LM339 but offers optimized performance characteristics for modern embedded systems. The PWR suffix specifically denotes the 14-lead Thin Shrink Small Outline Package (TSSOP) configuration.
