Nano-power comparators for gas, smoke, meters, and headsets

COSINE nano-power comparators are aimed at gas detectors, smoke/heat alarms, motion detectors, gas meters, position sensors, and headsets/earbuds. Stay here when Iq is hundreds of nA and microsecond response is acceptable; faster edges belong in the low-power or high-speed families.

Request datasheets from Jarwey.

Product features

Ultra-low quiescent current, low offset, wide supply range.

Applications (vendor-stated)

Gas detectors · smoke/heat alarms · motion detectors · gas meters · position sensors · headsets/earbuds.

Also listed: COS7031 / COS7041. Cross-tier PNs on some BOMs should be re-checked against the matching family.

Checklist before freeze

1. Gas / smoke / meter: is the average current budget truly nA-class?
2. Motion / position: is 3 µs OK with debounce?
3. Headset portables: push-pull COS7032 vs open-drain COS7042 and pull-up noise.
4. Supply: 1.6–5.5 V vs end-of-life battery voltage.
5. Samples: request datasheet and samples from Jarwey.
