MAX6424UK26+T

Product Overview

• Category: Integrated Circuit (IC)
• Use: Voltage Supervisor
• Characteristics: Low-power, precision voltage monitoring
• Package: SOT23-5
• Essence: Monitors the voltage level of a power supply and provides a reset signal when the voltage falls below a certain threshold.
• Packaging/Quantity: Tape and Reel, 3000 units per reel

Specifications

• Supply Voltage Range: 1.6V to 5.5V
• Reset Threshold Voltage: 2.63V
• Reset Timeout Period: 140ms
• Quiescent Current: 3µA (typical)
• Operating Temperature Range: -40°C to +85°C

Detailed Pin Configuration

The MAX6424UK26+T has a total of five pins:

1. GND: Ground connection
2. RESET: Active-low reset output
3. MR: Manual reset input
4. VCC: Positive supply voltage
5. TH: Threshold voltage input

Functional Features

• Precision voltage monitoring: The MAX6424UK26+T accurately monitors the voltage level of a power supply.
• Low-power operation: With a quiescent current of only 3µA, it minimizes power consumption.
• Reset signal generation: When the monitored voltage falls below the threshold, the IC generates an active-low reset signal.
• Manual reset capability: The MR pin allows for manual reset control.

Advantages and Disadvantages

Advantages: - High accuracy in voltage monitoring - Low power consumption - Small package size - Manual reset option

Disadvantages: - Limited supply voltage range (1.6V to 5.5V) - Fixed reset threshold voltage

Working Principles

The MAX6424UK26+T operates by comparing the voltage at the TH pin with a fixed threshold voltage. When the monitored voltage falls below this threshold, the IC generates an active-low reset signal on the RESET pin. The reset signal remains active until the voltage rises above the threshold or a manual reset is triggered.

Detailed Application Field Plans

The MAX6424UK26+T finds applications in various fields where precise voltage monitoring and reset functionality are required. Some potential application areas include:

1. Microcontrollers: Ensuring reliable operation by monitoring power supply voltage and initiating a reset if necessary.
2. Battery-powered devices: Preventing damage to sensitive electronics by providing a reset when battery voltage drops too low.
3. Industrial control systems: Enhancing system reliability by monitoring power supply integrity and triggering a reset during voltage fluctuations.

Detailed and Complete Alternative Models

1. MAX6425UK26+T: Similar to MAX6424UK26+T but with a different reset timeout period (e.g., 280ms).
2. MAX6426UK26+T: Offers adjustable threshold voltage for more flexibility in voltage monitoring applications.
3. MAX6427UK26+T: Provides additional features such as watchdog timer functionality and adjustable reset timeout.
