LM2901YPT

Overview

The LM2901YPT is a quad low-power voltage comparator manufactured by STMicroelectronics, housed in a 14-TSSOP surface-mount package. It operates from a single supply of 2 V to 32 V or dual supplies of ±1 V to ±16 V. Key electrical parameters include a typical supply current of 1.1 mA, input bias current of 25 nA, and input offset voltage of 7 mV. The device features a response time of 1.3 µs and an output saturation voltage of 250 mV at 4 mA load. It supports CMOS, DTL, ECL, MOS, and TTL compatible outputs and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Four independent precision comparators designed for wide single-supply operation with input common-mode range including the negative rail
• Low power consumption with supply current essentially independent of supply voltage magnitude
• Outputs compatible with various logic families including CMOS, DTL, ECL, MOS, and TTL
• Automotive grade qualification ensuring reliability in harsh environments

Applications

• Transducer amplifiers and signal conditioning circuits
• DC gain blocks in industrial control systems
• Sensor interface electronics
• Power management system monitoring

Procurement Notes

Verify the specific suffix YPT corresponds to the TSSOP-14 package and reel/cut-tape availability when ordering. Confirm AEC-Q100 automotive qualification requirements match the target application environment. Check RoHS compliance status against regional regulations. Ensure the operating temperature range of -40°C to +125°C suits the final system design constraints before procurement.

Selection Notes

Select this component when multiple independent comparators are needed within a single low-power footprint. The wide single-supply voltage range simplifies power distribution in systems lacking dual rails. The inclusion of negative rail common-mode capability allows direct interfacing with ground-referenced sensors without additional level shifting circuitry.

Part Context

This part belongs to the LM2901 series of low-power quad voltage comparators. It shares functional similarities with other members like the LM2901YDT but differs in packaging. The series is characterized by its ability to operate efficiently across a broad voltage spectrum while maintaining low static current draw, making it suitable for battery-powered and space-constrained designs.

Replacement Considerations

The LM2901YDT serves as a pin-compatible alternative offering identical electrical characteristics in a SOIC-14 package. Designers requiring a different footprint may consider this variant without modifying the schematic layout.
