Package

The MAX6422US22+T comes in a small SOT23-3 package, which is suitable for space-constrained applications.

Essence

The essence of the MAX6422US22+T lies in its ability to accurately monitor and control voltage levels, ensuring the proper functioning of electronic systems.

Packaging/Quantity

The MAX6422US22+T is typically available in tape and reel packaging, with a quantity of 3000 units per reel.

Specifications

• Supply voltage range: 1.8V to 5.5V
• Threshold voltage accuracy: ±1.5%
• Reset timeout period: 140ms (typical)
• Open-drain active-low reset output
• Power-on reset delay: 20ms (typical)

Detailed Pin Configuration

The MAX6422US22+T has three pins:

1. VCC: This pin is connected to the supply voltage.
2. GND: This pin is connected to the ground.
3. RESET: This pin provides the reset output signal.

Functional Features

• Voltage monitoring: The MAX6422US22+T continuously monitors the supply voltage and generates a reset signal if it falls below the threshold voltage.
• Reset generation: When the supply voltage drops below the threshold, the MAX6422US22+T asserts the reset output, indicating a power failure or voltage drop.
• Manual reset: The device also provides a manual reset input for external control of the reset signal.

Advantages and Disadvantages

Advantages

• Low quiescent current ensures minimal power consumption.
• Wide operating temperature range allows for use in various environments.
• Small package size enables integration into space-constrained designs.
• Accurate voltage monitoring ensures system reliability.

Disadvantages

• Limited voltage supervision range (2.2V).
• Lack of additional features compared to more advanced voltage supervisors.

Working Principles

The MAX6422US22+T operates by comparing the supply voltage with a fixed threshold voltage. If the supply voltage drops below the threshold, the device generates a reset signal. This signal can be used to initiate system shutdown or perform other necessary actions.

Detailed Application Field Plans

The MAX6422US22+T finds applications in various electronic systems where voltage monitoring and control are critical. Some potential application fields include:

1. Battery-powered devices: Ensuring proper voltage levels in portable electronics, such as smartphones and tablets.
2. Industrial automation: Monitoring voltage levels in control systems to prevent damage or malfunction.
3. Automotive electronics: Voltage supervision in automotive systems to maintain stable operation and protect sensitive components.
