Product Introduction

Overview

The TLV840MADL29DBVR from Texas Instruments is a nano-quiescent current voltage supervisor IC designed to operate over a wide input voltage range from 0.7 V to 6 V. This device is part of the TLV840 family, which is known for its low power consumption, high accuracy, and low propagation delay. The TLV840MADL29DBVR is particularly suited for applications requiring precise voltage monitoring and reset functionality with minimal current draw.

Key Features

  • Programmable reset time delay using an external capacitor (CT pin)
  • Active-low manual reset (MR pin) for TLV840M variants
  • High accuracy threshold voltage with built-in hysteresis
  • Low power-on reset voltage (VPOR) and glitch immunity protection for VDD
  • Low open-drain output leakage current (Ilkg(OD))
  • Four output topologies: open-drain active-low, push-pull active-low, open-drain active-high, push-pull active-high

Applications

  • Motor Drives
  • Factory Automation and Control
  • Home Theater and Entertainment
  • Electronic Point of Sale
  • Grid Infrastructure
  • Data Center and Enterprise Computing
  • Multifunction Printers
  • Automotive systems such as surround view systems, front cameras, automotive gateways, radar ECUs, and ADAS controllers

Q & A

  1. What is the operating voltage range of the TLV840MADL29DBVR? The operating voltage range is from 0.7 V to 6 V.
