TLV1831DCKR TI Comparator | SC-70-5 | 4.5-5.5V, 1.8µA

Product Overview

The TLV1831DCKR from Texas Instruments is a single-channel, low-power comparator designed for precision voltage sensing in space-constrained applications. Housed in a compact SC-70-5 package, it operates from a supply voltage range of 4.5V to 5.5V and features an ultra-low quiescent current of 1.8µA (typical). The device offers rail-to-rail input common-mode voltage range and open-drain output, making it ideal for battery-powered systems and portable electronics.
