LM2901QPWRQ1 in LM339 / LM393 Comparators Family
The LM2901QPWRQ1 belongs to the industry-standard LMx39/LMx93 family of voltage comparators, manufactured by Texas Instruments and other leading semiconductor suppliers. These devices consist of four independent voltage comparators designed specifically to operate from a single power supply over a wide range of voltages. Primarily used in automotive and industrial applications, they feature an open-collector output that allows for logical wired-AND connections and level shifting between different voltage rails.
Variants in This Sub-Family
Variants within this sub-family primarily differ by their temperature grade, package type, and automotive qualification status. The 'Q1' suffix indicates AEC-Q100 qualification, while the 'A' or 'B' versions often offer improved input offset voltage specifications. Packaging options range from standard SOIC and TSSOP to smaller VQFN footprints, allowing designers to balance thermal dissipation requirements against available PCB real estate in space-constrained designs.
