Overview

The TLV3404IDR is a quad-channel, ultra-low power comparator designed specifically for battery-powered systems requiring extremely low standby current. Consuming just 0.47 microamps per channel, it operates over a wide supply range of 2.7V to 16V with an open-drain output stage. This device is ideal for monitoring signals in remote or handheld environments where power efficiency is the primary design constraint.

Why Choose This Part

The primary advantage is the industry-leading 0.47 microamp supply current, which allows for 'always-on' monitoring without depleting batteries. It supports a wide input voltage range up to 21V and features an open-drain output, making it easy to interface with different logic levels up to 16V regardless of the comparator supply voltage.

Applications

Portable Medical Equipment
Used in battery-operated diagnostic tools where minimizing idle power consumption is critical for long shelf life.
Wireless Security Sensors
Ideal for window and door contact sensors that must operate for years on a single coin cell.
Remote 4-20mA Loop Monitoring
Provides threshold detection in industrial loops without significantly impacting the current budget.
Handheld Instrumentation
Functions as a low-battery indicator or wake-up trigger for power-sensitive digital multimeters and testers.

Getting Started

When designing with this part, ensure the high-impedance inputs are protected from leakage currents on the PCB, which can exceed the device's own supply current. Use a pull-up resistor on the open-drain output suited for your logic level, typically ranging from 10k to 1M ohms depending on the required speed. For prototyping, the 14-SOIC package can be used with standard SOIC-to-DIP adapter boards on a breadboard.
