TLV840NAPL50DBVR TI Supervisory Circuit | SOT-23-5 | 4.0V Threshold, Active-Low Reset

Product Overview

The TLV840NAPL50DBVR from Texas Instruments is a low-power supervisory circuit designed for monitoring power supply voltages in microprocessor and digital systems. It provides a precision voltage threshold of 4.0V (typical) and asserts a reset signal when VDD falls below this threshold, ensuring reliable system startup and shutdown. The device features an active-low, open-drain RESET output that remains valid for VDD as low as 0.7V. Housed in a compact SOT-23-5 package, it is ideal for space-constrained applications requiring high accuracy and low quiescent current (typically 5µA).

Detailed Technical Specifications

Key Features

• Precision voltage monitoring with 1.5% accuracy over temperature
• Low quiescent current of 5µA extends battery life
• Open-drain RESET output allows wired-OR connection
• Guaranteed RESET valid down to VDD = 0.7V
• 200ms reset timeout period ensures system stabilization
• Small SOT-23-5 package saves board space

Target Applications

• 5G base station power supply monitoring
• Automotive dashboard and infotainment systems
