TS391RILT ST Comparator | SOT-23-5 | Low Power, Open Collector

Product Overview

The TS391RILT is a low-power, single-channel voltage comparator manufactured by STMicroelectronics. Housed in a compact SOT-23-5 package, it is designed for applications requiring precision voltage comparison with minimal power consumption. The device features an open-collector output, making it suitable for interfacing with various logic families and driving loads such as relays or LEDs. With a wide supply voltage range from 2V to 36V (or ±1V to ±18V for dual supplies), the TS391RILT offers flexibility in both single and dual supply operations. Its low supply current of 0.4mA typical ensures energy efficiency, ideal for battery-powered and portable devices.
