TLV840CADL28DBVR TI Voltage Supervisor | SOT-23-5 | 2.8V Threshold, Active-Low Open-Drain

Product Overview

The TLV840CADL28DBVR is a voltage supervisor from Texas Instruments, designed for precise monitoring of power supply voltages. It features a fixed threshold voltage of 2.8V with an active-low, open-drain reset output. Housed in a compact SOT-23-5 package, this device ensures reliable system reset during power-up, power-down, and brown-out conditions. With a low quiescent current of typically 5.5 µA, it is ideal for power-sensitive applications. The TLV840 family offers high accuracy (±1% at 25°C) and a wide operating voltage range of 0.7V to 6V, making it suitable for various electronic systems.
