Detailed Pin Configuration

The ADM6328-26ARTZ-R7 has the following pin configuration:

1. VCC: Supply voltage input
2. GND: Ground reference
3. MR: Manual reset input
4. RESET: Active-low reset output

Functional Features

• Precision voltage monitoring: The ADM6328-26ARTZ-R7 accurately monitors the supply voltage and provides a reset signal when it falls below the specified threshold.
• Manual reset input: It includes a manual reset input (MR) that allows an external signal to force a reset condition.
• Active-low reset output: The device provides an active-low reset output (RESET) that can be connected to the reset input of the microcontroller or other devices.

Advantages and Disadvantages

Advantages

• Accurate voltage monitoring ensures reliable operation of electronic circuits.
• Manual reset input allows for external control over the reset condition.
• Small package size (SOT-23) enables space-saving designs.

Disadvantages

• Limited voltage supervision range (2.6V).
• Reset timeout period may not be suitable for all applications.

Working Principles

The ADM6328-26ARTZ-R7 operates by comparing the supply voltage with a fixed threshold voltage. When the supply voltage falls below the threshold, the reset output is activated, indicating a low-voltage condition. The manual reset input allows an external signal to override the monitoring circuit and force a reset condition.

Detailed Application Field Plans

The ADM6328-26ARTZ-R7 can be used in various applications, including:

1. Battery-powered devices: It ensures proper operation and prevents damage due to low battery voltage.
2. Microcontroller systems: It provides reliable reset signals during power-up and voltage fluctuations.
3. Industrial control systems: It monitors power supply integrity and initiates system resets when necessary.
4. Automotive electronics: It safeguards sensitive components from voltage drops and ensures proper functioning.

Detailed and Complete Alternative Models

Some alternative models that offer similar functionality to ADM6328-26ARTZ-R7 are:

1. MAX809: Precision voltage supervisor with manual reset input.
2. LTC2937: Dual voltage monitor with adjustable thresholds and manual reset input.
3. TPS3839: Ultra-low-power voltage supervisor with manual reset input.

These alternatives provide different voltage thresholds, package options, and additional features, allowing designers to choose the most suitable option for their specific application.
