LM2901QS14-13

Overview

The LM2901QS14-13 is an automotive-compliant quad differential comparator from Diodes Incorporated, housed in a 14-pin SOIC package. It operates on single supplies from 2V to 36V or dual supplies of ±1V to ±18V. The device features very low supply current independent of voltage, with a typical drain of 0.9mA at 5V. It offers low input bias current (25nA), low offset voltage (7mV max), and open-collector outputs compatible with TTL, MOS, and CMOS logic.

Feature Summary

• Qualified to AEC-Q100 Grade 1 standards for automotive applications
• Wide power supply range supporting both single and split configurations
• Low quiescent current consumption that remains stable across varying voltages
• Open-collector outputs allowing direct interface with various digital logic families

Applications

• Automotive sensor signal conditioning
• Voltage monitoring circuits
• Logic level translation between different voltage domains
• Threshold detection systems

Procurement Notes

Verify the specific suffix 'S14' corresponds to the SO-14 package configuration required for your PCB layout. Confirm the '-13' designation aligns with tape and reel packaging specifications. Ensure the component meets RoHS and halogen-free requirements if mandated by your assembly process. Cross-reference the datasheet revision date against your design timeline.

Selection Notes

Select this part when high reliability in automotive environments is required. The quad configuration allows multiple comparisons within a single footprint. Consider the open-collector output requirement for pull-up resistor implementation. Verify that the 36V maximum rating covers your system's peak voltage conditions.

Part Context

This component belongs to the LM2901Q series, designed specifically for automotive use. It shares functional similarities with standard industrial comparators but includes enhanced qualification testing. The quad architecture provides four independent channels, maximizing board space efficiency compared to using individual dual or single comparator packages.

Replacement Considerations

LM2901QT14-13 serves as a pin-compatible alternative utilizing a TSSOP-14 package instead of SO-14. Designers must verify thermal dissipation characteristics and physical footprint differences when substituting between SO and TSSOP variants.
