TL391LVQDBVRQ1 TI Low-Voltage Comparator | SOT-23-5 | 2.7V-5.5V, Open-Drain Output

Product Overview

The TL391LVQDBVRQ1 is a low-voltage, low-power comparator from Texas Instruments, designed for automotive and industrial applications. It operates from a single supply voltage of 2.7V to 5.5V, making it ideal for battery-powered and portable devices. The device features an open-drain output that can be pulled up to any voltage up to 5.5V, independent of the supply voltage. With a typical propagation delay of 1.3 µs and a low supply current of 20 µA per channel, the TL391LVQDBVRQ1 offers excellent performance for power-sensitive designs. The SOT-23-5 package ensures a compact footprint for space-constrained applications.
