TLV1812QDRQ1 TI Comparator | 8-SOIC | 40V, 1.8V to 40V, Open-Drain Output

Product Overview

The TLV1812QDRQ1 is a high-voltage, automotive-grade comparator from Texas Instruments, designed for robust performance in harsh environments. It operates over a wide supply range of 1.8V to 40V and features an open-drain output that can be pulled up to any voltage up to 40V, independent of the supply. This device is AEC-Q100 qualified for automotive applications, ensuring reliability under extreme conditions. The TLV1812QDRQ1 offers low quiescent current (typical 1.5µA) and fast propagation delay (typical 1.5µs), making it suitable for power management, overvoltage/undervoltage detection, and signal conditioning in automotive and industrial systems.
