What seals this comparator into an automotive BOM
The wide single-supply range from 2V to 36V lets this comparator sense directly on a 12V or 24V battery rail without a preregulator, which saves a BOM line and keeps the supply current at 2.5mA max quiescent.
Output flexibility and drive capability
The outputs are open-collector compatible with CMOS, MOS, and TTL logic families, so the comparator interfaces directly to a microcontroller GPIO or a gate driver without a level-shift stage. Input offset voltage is specced at 7mV max at 5V, which is the parametric limit the test engineer will check against the application threshold — tighter than the generic LM393 family.
Housed in an 8-TSSOP package with 0.65mm pin pitch — the footprint fits a standard SOIC-8 land pattern with a slight pad width adjustment, so a layout engineer can reuse an existing dual-op-amp footprint with a minor stencil revision. Surface-mount only; the Tape & Reel option (TR suffix) is the production-friendly format for automated pick-and-place, while Cut Tape (CT) suits prototype runs.
Base product number LM2903 has been in continuous production across multiple temperature and package variants — this V-grade (-40°C to 125°C) is the automotive-tier option and sees steady demand, not a niche short-run suffix.
