MAX6893ETI+T

Product Overview

Category

The MAX6893ETI+T belongs to the category of voltage supervisors and monitors.

Use

It is used to monitor power supply voltages in microprocessor systems and provide a reset signal to the microprocessor during power-up, power-down, and brownout conditions.

Characteristics

• Voltage Monitoring: Monitors up to four power supply voltages.
• Reset Output: Provides a reset signal when any monitored voltage drops below its preset threshold.
• Low Power Consumption: Consumes minimal power, making it suitable for battery-powered applications.
• Adjustable Reset Threshold: Allows flexibility in setting the voltage threshold for triggering the reset signal.

Package

The MAX6893ETI+T is available in a 28-pin thin QFN package.

Packaging/Quantity

It is typically supplied in tape and reel packaging with a quantity of 2500 units per reel.

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Operating Temperature Range: -40°C to +85°C
• Reset Timeout Period: Adjustable from 1.6ms to 6.4s
• Reset Active-Low Output: Open-drain output capable of sinking 10mA

Detailed Pin Configuration

The detailed pin configuration of MAX6893ETI+T is as follows:

| Pin Number | Pin Name | Description | |------------|-------------|---------------------------------------| | 1 | VCC | Supply Voltage | | 2 | MR | Manual Reset Input | | 3 | RESET | Reset Output | | ... | ... | ... | | 28 | GND | Ground |

Functional Features

• Multi-Voltage Monitoring: Monitors up to four different power supply voltages simultaneously.
• Adjustable Reset Timeout: The reset timeout period can be adjusted to suit specific application requirements.
• Manual Reset Input: Allows for manual initiation of the reset signal through the MR pin.

Advantages and Disadvantages

Advantages

• Flexible voltage monitoring for multi-rail systems.
• Low power consumption.
• Adjustable reset timeout period for customization.

Disadvantages

• Limited to monitoring up to four power supply voltages.

Working Principles

The MAX6893ETI+T operates by continuously monitoring the input voltages and comparing them to the preset threshold levels. When any monitored voltage falls below its respective threshold, the device asserts the reset output, which remains active until the voltage rises above the threshold or the reset timeout period elapses.

Detailed Application Field Plans

The MAX6893ETI+T is commonly used in embedded systems, industrial control systems, automotive electronics, and portable devices where reliable power supply monitoring and reset functionality are critical.

Detailed and Complete Alternative Models

Some alternative models to MAX6893ETI+T include MAX809, MAX811, and MAX6715, each offering similar voltage monitoring and reset functionalities with varying specifications and package options.

In conclusion, the MAX6893ETI+T provides a comprehensive solution for voltage monitoring and reset generation in microprocessor systems, offering flexibility, reliability, and low power consumption.
