TLV840CADL40DBVR TI Supervisory Circuit | SOT-23-5 | 4.0V Threshold, Active-Low Reset

Product Overview

The TLV840CADL40DBVR from Texas Instruments is a supervisory circuit (voltage detector) designed for monitoring power supply voltages in digital systems. It provides a reset output when the supply voltage drops below a preset threshold, ensuring reliable system operation during power-up, power-down, and brownout conditions. Housed in a compact SOT-23-5 package, this device is ideal for space-constrained applications requiring precise voltage monitoring with low power consumption.
