MAX6711LEXS+T

Product Overview

• Category: Integrated Circuit (IC)
• Use: Voltage Monitor
• Characteristics: Low-power, precision voltage monitor with adjustable threshold
• Package: SOT23-5
• Essence: Monitors the voltage level of a power supply and provides an output signal when it falls below a user-defined threshold
• Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

• Supply Voltage Range: 1.6V to 6.5V
• Adjustable Threshold Voltage Range: 1.22V to 5.5V
• Quiescent Current: 3µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6711LEXS+T has a total of five pins:

1. GND: Ground connection
2. IN: Input voltage to be monitored
3. SET: Threshold voltage adjustment pin
4. RESET: Active-low reset output
5. VCC: Power supply input

Functional Features

• Precision Monitoring: The MAX6711LEXS+T accurately monitors the input voltage and compares it to the user-adjustable threshold voltage.
• Adjustable Threshold: The SET pin allows users to set the desired threshold voltage within the specified range.
• Reset Output: When the input voltage falls below the threshold, the RESET pin goes low, indicating a power failure or undervoltage condition.
• Low Power Consumption: With a quiescent current of only 3µA, the MAX6711LEXS+T minimizes power consumption in battery-powered applications.

Advantages and Disadvantages

Advantages: - High accuracy voltage monitoring - Adjustable threshold for flexibility - Low power consumption - Small package size for space-constrained designs

Disadvantages: - Limited operating temperature range (-40°C to +85°C) - Single-channel monitoring (not suitable for multi-channel applications)

Working Principles

The MAX6711LEXS+T operates by comparing the input voltage with the threshold voltage set by the user. When the input voltage falls below the threshold, the RESET pin goes low, indicating an undervoltage condition. The device continuously monitors the voltage and provides a reliable output signal.

Detailed Application Field Plans

The MAX6711LEXS+T is commonly used in various applications, including:

1. Battery-Powered Devices: It ensures proper power supply voltage levels, preventing damage to sensitive components during low battery conditions.
2. Power Management Systems: It provides undervoltage protection, triggering system resets or shutdowns when the power supply drops below the specified threshold.
3. Industrial Control Systems: The voltage monitor helps maintain stable operation of critical equipment by detecting power supply failures or fluctuations.

Detailed and Complete Alternative Models

1. MAX6710LEXS+T: Similar to MAX6711LEXS+T but with a fixed threshold voltage of 4.63V.
2. MAX6712LEXS+T: Similar to MAX6711LEXS+T but with a wider operating temperature range (-40°C to +125°C).
