TLV3012BQDBVRQ1 TI Comparator | SOT-23-6 | 1.8V-5.5V, 1.65V Ref

Product Overview

The TLV3012BQDBVRQ1 from Texas Instruments is a low-power, open-drain output comparator with an integrated 1.65V series voltage reference. Housed in a compact SOT-23-6 package, this device operates over a wide supply range of 1.8V to 5.5V, making it ideal for battery-powered and automotive applications. The comparator features a typical quiescent current of only 1.5µA, ensuring minimal power consumption. The integrated reference provides a stable 1.65V output with an initial accuracy of ±1% and a temperature coefficient of 50ppm/°C. The open-drain output allows for wired-OR configurations and level shifting. The TLV3012BQDBVRQ1 is qualified for automotive applications (AEC-Q100) and is specified over the –40°C to +125°C temperature range.
