TS391IYLT ST Comparators

The TS391IYLT is an automotive-grade (AEC-Q100) low-power single voltage comparator from STMicroelectronics in SOT-23-5 package, operating from 2V to 34V single supply or ±1V to ±17V dual supplies. For selection, verify supply voltage range, confirm low supply current of 250 µA typical for power-sensitive designs, note response time of 1.3 µs typical, input offset voltage of 2 mV max, input bias current of 25 nA typical, and operating temperature from -40°C to +125°C with automotive qualification. Features include low power consumption for extended battery life, rail-to-rail input capability, and open-collector output for wired-OR connections. Ideal for automotive battery-powered portable devices, threshold detectors, level shifting circuits, zero-crossing detectors, window comparators, sensor interfaces, and any low-power analog comparison application requiring automotive-grade reliability and small SOT-23-5 footprint.
