Product details

It packs four independent comparators into a 14-SOIC package, each with an open-collector output that can sink up to 20 mA typical.

Open-collector output and input offset budget

Maximum input offset voltage is 7 mV at 5 V supply, which sets the threshold accuracy floor for over-voltage or under-voltage detection on the battery line. Quiescent current maxes at 2.5 mA across all four channels, keeping the standing draw low in always-on ECU modules.

AEC-Q100 and active lifecycle

For automotive programs that require a documented qualification flow and long-term supply assurance, this part avoids the last-time-buy risk that NRND or EOL comparators introduce.

Frequently asked questions

Is LM2901VQDRG4Q1 a direct replacement for LM2901?

The LM2901VQDRG4Q1 is a variant of the base LM2901 family. The 'V' suffix denotes a wider supply range (2 V to 36 V) and the 'Q1' suffix indicates AEC-Q100 automotive qualification. It is pin-compatible with standard LM2901 devices in the same 14-SOIC footprint, but the automotive-grade temperature range and qualification should be verified against the original BOM requirement.

Is LM2901VQDRG4Q1 automotive qualified?

Yes, the LM2901VQDRG4Q1 is part of the Automotive, AEC-Q100 series. This means it has undergone the stress and reliability testing required for automotive-grade components, including the -40°C to 125°C operating temperature range.
